publish.yml replaces .github/workflows/publish.yml: on a v* tag it checks the
tag equals v<brand_version!> and is on main, builds the linux/amd64+arm64
image in one buildx run (the Dockerfile already cross-compiles, so only its
final stage goes through QEMU), pushes :<version> and :latest to the
registry, links the package, and creates the tag's release if it has none.
weekly-release.yml ports .github/workflows/release.yml: bump brand_version!
through the contents API, then create the release and so the tag, which
starts publish.yml. It only dry-runs until RELEASE_LIVE=1 and a
RELEASE_TOKEN secret exist.
GitHub took the organization's repos and GHCR offline on 2026-09-20. Repo,
release, raw-file and clone links now go to Gitea at git.coffeylabs.org,
container images to registry.coffeylabs.org, and GitLab-style /-/blob paths
to Gitea's /src/branch form. Go module paths are identifiers and stay as
they are; links to GitHub issues and pull requests are left as history.
The build now mounts the named volume inbuxa-server-cargo at /cache and keeps
CARGO_HOME and CARGO_TARGET_DIR there, so a push reuses the compiled
dependency tree (RocksDB included) instead of rebuilding it from scratch.
Both runners allow that one volume; each host keeps its own copy.
With the cache in place the job moves to runs-on: light, so it can run on
host2 as well. Cargo's parallelism now follows the job's CPU cap rather than
the host's core count, and the target dir is dropped past 25 GB.
Deleting a tenant now also removes its stored inbuxa:TenantProtocolPolicy,
in the same place the registry's other per-type clean-ups run. Without it
the row outlived the tenant, and a tenant that later came to have the same
id would have started with legacy protocols off.
The e2e deletes a tenant whose switch a server administrator had turned
off, and would check that a new tenant with the same id starts with them
on. On this build the registry hands out a fresh id instead ("d" after
"c"), so the reuse -- and with it the removal -- isn't observable over
JMAP; the test says so rather than passing silently. The risk it guards
was therefore smaller than feared, and the change is mostly about not
leaving an orphaned row behind. All 72 checks pass.
The Hardening link merged to main changed the packaged schema, which this
branch also changes. The file is gzipped, so the two can't be merged line
by line: this takes main's schema and adds security.legacy-protocols-changed
to it again, with the hash recomputed.
The impact panel's data. Every successful sign-in over IMAP, POP3,
ManageSieve or SMTP AUTH records, per account and per protocol, one
timestamp -- nothing else: no address, no IP, no client. It is written at
most once an hour per account and protocol, so a mail app polling every
minute costs a read per sign-in and a write an hour. A record that can't be
written is logged and the sign-in goes ahead.
Both switches serve it as a read-only property, recentLegacyUse, as
wouldClose serves the confirmation: a list of {accountId, name, protocol,
lastUsedAt} for sign-ins in the last 30 days, most recent first.
inbuxa:ProtocolPolicy lists every account; inbuxa:TenantProtocolPolicy
lists only its tenant's own (MT-1). Accounts since deleted are left out. It
is computed only when the property is asked for.
The recording sits where the tenant check already runs once the account is
known, which becomes admit_legacy_session: refuse if the account's tenant
has legacy protocols off, otherwise record. A refused sign-in is never
recorded.
The spec leaves the interface to the implementation; a property on each
switch keeps the panel's data behind the same permission as the switch
itself, with no new object.
Unit tests hold the 30-day window to acceptance test 11 (three days ago
listed, forty not), the hourly throttle and the keys. The e2e proves on a
running server that the admin's IMAP and submission sign-ins are listed
with their time, that a second sign-in within the hour isn't written again,
and that a tenant's list holds its own user and nobody outside the tenant.
All 70 checks pass.
The urn:inbuxa:jmap capability on the signed-in principal's own account
gains legacyProtocols: "enabled" or "disabled", the stricter of the
server's switch and the account's tenant's (legacy-protocols spec,
Interfaces). It is what the webmail needs to tell someone why their phone's
mail app won't connect (LP-19), and it closes acceptance test 13.
contract.md's C-1 gains the line. It is an optional field added, which
C-3 says doesn't bump the contract version.
tests/e2e/legacy_protocols.py reads it back from the session on a running
server: enabled for the tenant's user while both switches are on, disabled
once its tenant turns legacy protocols off while an account outside the
tenant still reads enabled, disabled for everyone while the server switch
is off, and enabled again at the end. All 67 checks pass.
The tenant switch. A tenant's administrator turns legacy mail protocols
off for its own tenant, and from then on sign-in over IMAP, POP3,
ManageSieve and SMTP AUTH is refused for every address on the tenant's
domains, while every other domain on the server carries on. No port
closes, since other tenants share them (LP-13): it is one stored fact per
tenant, read at sign-in and when client configuration is answered.
inbuxa:TenantProtocolPolicy/get and /set, one per tenant, id the tenant's:
- Inside a tenant, a principal reaches only its own tenant's switch
(MT-1): /get with no ids answers with it, another tenant's is notFound
and can't be changed. At server level /get with no ids lists every
tenant's.
- Turning it off is always allowed. Turning it back on is refused with
forbidden, naming inbuxa:ProtocolPolicy, while the server has legacy
protocols off (LP-9).
- A change raises security.legacy-protocols-changed with policy = tenant,
the tenant's id, the new value and who made it (LP-14).
- It takes sysDomainGet and sysDomainUpdate, not the two new permissions
the spec names. The switch governs sign-in on the tenant's domains, so
whoever manages those domains may turn it -- and the default Tenant
Administrator role already holds both, where new permissions would reach
no role already stored on a server (MT-12's note), leaving today's
tenant administrators without the switch until someone edited their
role by hand. The same trade inbuxa:AiLimits and inbuxa:ProtocolPolicy
made. /query is not built yet; /get with no ids covers listing.
Sign-in (LP-10 to LP-12). Before the credentials are looked at, the name
given is resolved to its domain and the domain to its tenant, so a real
account and a made-up address on the domain get the same refusal, with a
right password or a wrong one, counted as no failed sign-in (LP-11). The
words are the spec's: "Your organization allows only INBUXA webmail and
JMAP apps...", in each protocol's form. A bearer token needn't name an
account, so after authentication the account's own tenant is checked too;
a token that named nobody can't slip past.
The refusal carries policy = tenant and the domain, not the tenant's id:
IMAP answers a command's tag from the Id key, so an error holding one was
sent under the wrong tag and the mail app hung waiting for its reply. The
first live run found that; a unit test now holds the refusal to it.
Client configuration (LP-14a). Autoconfig, autodiscover, PACC and the
suggested DNS records now ask whether legacy services are off for the
domain being answered for -- the server's switch, or the domain's
tenant's -- so a tenant's domains stop offering IMAP, POP3 and
submission while others still do.
tests/e2e/legacy_protocols.py builds a tenant with its own domain, a user
and a tenant administrator, and a second tenant, and proves on a running
server: the admin sees and changes only its own tenant's switch (test 10);
turning it off is an event (test 14); the tenant's user is refused over
IMAP with the right password and a wrong one, a made-up address on the
domain the same (tests 6, 7); POP3 and submission refuse in their own
forms and JMAP still works (test 8); an account on another domain signs in
normally (test 6); autoconfig drops IMAP for the tenant's domain only; with
the server off, the tenant can't turn it back on (test 9); and once back
on, the user signs in again. All 62 checks pass.
Turning legacy mail protocols off or back on raises
security.legacy-protocols-changed (id 643, info level, also in the packaged
schema), with the scope (policy = server), the new value, who made the
change (accountId), whether listeners closed or reopened (details), which
ones (listenerId), and -- only when a listener could not be put back --
which and why (reason).
It is raised in Server::set_protocol_policy rather than by the JMAP
method, so whatever turns the switch is reported. A /set that changes
nothing -- the switch already where it was asked to be, nothing to close
or reopen -- is not a change and raises nothing.
The event is never an error, but jmap's exhaustive map from security
events to HTTP errors has to name it; it joins the other two that can't
occur there. rustfmt now also wraps LP-6's two over-long lines in
enums_impl.rs, which it flagged along with this change's.
tests/e2e/legacy_protocols.py now gives the server a stdout tracer and
reads events from the container's log: turning the switch off is exactly
one event naming the scope, value, author and listeners closed; setting it
off again raises none; turning it on is one event naming the listeners
reopened. It also proves LP-6's side: seven refused submission sign-ins
are seven auth.legacy-protocol-refused events, and there is no auth.failed
or auth.too-many-attempts among them. All checks pass.
While the switch is off, the answers that tell a mail app where to connect
stop offering what the switch closed, so a new phone or desktop app is not
sent to a port that is shut or a sign-in that will be refused:
- Thunderbird-style autoconfig (/mail/config-v1.1.xml and its other
paths) and Outlook autodiscover leave out IMAP, POP3 and SMTP
submission.
- PACC (/.well-known/user-agent-configuration.json) offers JMAP, CalDAV,
CardDAV and WebDAV, and no IMAP, POP3, SMTP or ManageSieve. The document
is rendered once per configuration load, so the JMAP-only version is
rendered beside it and chosen per request; the _ua-auto-config digest in
the suggested zone follows, since it hashes the same document.
- The suggested zone publishes _imap, _imaps, _pop3, _pop3s, _submission
and _submissions with target "." -- "not offered", RFC 6186 section 3.4 --
the spec's decision, rather than dropping them: a client that looks is
told, and an automatically managed zone replaces the old records instead
of leaving them behind.
- It also drops the TLSA records for ports 993 and 995. A TLS pin for a
port the switch has closed advertises a service that is not there.
Submission's 465 keeps its record: the SMTP lock keeps that port open.
The switch is read per answer, as sign-in reads it, so every node agrees
the moment it turns. Inbound mail, MX records and the JMAP, CalDAV and
CardDAV answers are untouched.
tests/e2e/legacy_protocols.py checks all four on a running server: with the
switch on they offer IMAP, POP3 and SMTP (the control); while it is off
they offer none of them and every legacy SRV name has target "."; and once
it is back on, autoconfig and the zone read as they did before. All checks
pass.
LP-6 added auth.legacy-protocol-refused to the packaged schema, which this
branch also changes. The file is gzipped, so the two can't be merged line
by line: this takes main's schema and adds the Settings › Security ›
Hardening link to it again, with the hash recomputed.
While legacy mail protocols are off, x:NetworkListener/set refuses to
create a listener the switch would close, and refuses an update that would
turn an existing one into such a listener -- otherwise changing a
listener's protocol would walk straight past the check. The refusal is
invalidProperties on protocol (or on bind, for a submission listener once
SMTP is unlocked, since its port is what makes it one), and its description
names inbuxa:ProtocolPolicy and says to turn legacy protocols back on first.
The rule is the switch's own, listeners::closes, so what can't be added is
exactly what the switch would close: locked protocols (SMTP, LMTP, HTTP)
and the inbound port are never refused. Putting saved listeners back
(LP-5) writes through the registry, not /set, so it is unaffected.
The e2e changes with it. LP-6's check that an IMAP listener "created by
mistake" refuses sign-in can't be set up any more -- LP-4 is what stops
that listener existing -- so that step now proves test 4 instead: creating
an IMAP listener is refused, naming the policy; an SMTP listener can still
be created; and updating it to IMAP is refused. LP-6 stays proven live over
submission, and its IMAP wording by unit tests. All checks pass.
The second lock. While legacy mail protocols are off, a sign-in over IMAP,
POP3, ManageSieve or SMTP AUTH is refused for every account, so a listener
that exists by mistake -- or submission, which the SMTP lock keeps open --
still lets nobody in.
The check sits at the top of each protocol's sign-in, before the
credentials are looked at. So the answer is the same for a right password,
a wrong one and an account that doesn't exist; it isn't auth.failed, so it
counts nothing against the account and never feeds the auto-ban; and the
session stays open, since the mail app is being told, not thrown off.
Mail apps read the spec's words (LP-12, at server scope):
IMAP NO [ALERT] This server allows only INBUXA webmail and JMAP
apps. This mail app can't sign in.
POP3 -ERR [AUTH] ...the same...
ManageSieve NO "This server allows only INBUXA webmail and JMAP apps."
SMTP 535 5.7.0 This server allows only INBUXA webmail and JMAP
apps. This mail app can't send.
SMTP AUTH is refused on every SMTP listener, port 25 included: only mail
apps authenticate, so inbound delivery is untouched. LMTP is left alone.
The policy is read from the store on each sign-in rather than cached, so
every node of a cluster answers the same the moment the switch turns.
Each refusal raises a new event, auth.legacy-protocol-refused (id 642, info
level, also in the packaged schema), with the protocol as source, the
policy's scope and the domain -- never the account. The session adds the
listener and remote IP.
tests/e2e/legacy_protocols.py now also proves, on a running server: a
normal IMAP and submission sign-in works with the switch on, before and
after; while off, submission refuses the right password and six wrong ones
with the same words and without hanging up; and an IMAP listener created by
mistake while off refuses the right password, a wrong one and an account
that doesn't exist. All 33 checks pass. SMTP sign-ins in the script wait
out a second first: every connection arrives from Docker's gateway, and the
stock inbound throttle takes five a second from one IP.
Adds a link to CustomComponent/LegacyProtocols in the packaged schema's
Settings › Security, between Settings and Blocked IPs, and updates the
schema hash so admins fetch the new layout rather than a cached one.
INBUXA Admin draws the screen; this is what makes it reachable. An admin
from before that screen would show "Unknown component" here, so this
lands after the admin release that carries it.
Ports .github/workflows/ci.yml after the GitHub account was suspended and
Actions stopped being reachable. Same checks, same order, with the image
pinned by digest in place of the workflow's SHA-pinned actions.
cleanup.yml is not ported: it pruned GHCR through an action, and GitLab
keeps that as a container registry cleanup policy on the project rather
than as a pipeline. publish.yml and release.yml are larger and follow
separately.
The Actions workflows stay in the tree as the reference.
.gitignore blanket-ignores dotfiles, so .gitlab-ci.yml is negated there the
same way .github already is.
main is protected as of today -- no force-push, no deletion, and a pull
request with a green build to merge -- and GITHUB_TOKEN is not a bypass
actor. `git push origin HEAD:main` in the cut job would have been refused
from Monday, on a scheduled run nobody watches.
GitHub would not take the obvious fix. Adding the Actions integration as a
bypass actor is rejected ("must be part of the ruleset source or owner
organization") because the organization has no app installations. The
other two routes -- an organization-level ruleset, a deploy key with write
access -- both amount to handing the release a credential that outranks
the rule, which is a worse thing to own than a slower Monday.
So the bump lands the way every other change does. It commits to
release/v<version>, opens a pull request, waits for the build the ruleset
requires, merges, and tags what came out. The waiting is not merely the
rule being satisfied: a release cut from a tree that does not compile is
the failure this whole arrangement exists to prevent, and until now
nothing checked.
Three details that would each have produced a wrong tag. The sha comes
from GitHub's merge commit, not the tip that was pushed, because a rebase
merge rewrites it. The pull request is tracked by number, not by branch,
because the branch is deleted on merge and a deleted branch no longer
resolves to its pull request. And a failed or slow build leaves the pull
request open and cuts nothing, rather than tagging whatever main happened
to hold.
Quiet weeks are unaffected: the tag still names the bump commit, so
`previous..HEAD` is still zero when nothing else has landed.
The cost is a Monday run that now takes as long as a full build -- about
25 minutes at the moment, most of it saving the cache.
main has a ruleset as of today: no force-push, no deletion, and a pull
request with a green build to merge. CONTRIBUTING said nothing about any
of it, and a contributor's first clue would have been a rejected push.
No approving review is required. A review gate nobody can pass is not a
gate, and this is a project with one maintainer; the build is the part
that has to hold.
The section also says why the rule exists rather than only what it is.
The weekly release cuts from main on a Monday and ships whatever is there,
so main is expected to be releasable continuously -- which makes "not
finished" a thing that belongs behind a default-off switch or off main
altogether, not a state main passes through on a Thursday.
Administrators can bypass. That is written down as being for correcting
the tree, not for skipping the path, because an undocumented bypass
becomes the normal route.
tests/e2e/legacy_protocols.py boots the debug binary in a container, turns
the switch off and on, and checks the ports themselves. Everything below it
was unit-tested and none of it could have told us this worked.
What it establishes: IMAP and POP3 stop answering while inbound SMTP,
submission and JMAP keep going (LP-1, LP-2, LP-3); the listeners are saved
whole (LP-1); a restart does not reopen them, which is the point of taking
the objects away rather than only the sockets; both come back on their own
without a restart (LP-5); savedListeners empties; and asking to close
submission is overruled to false and reported, with 465 still answering
(LP-21, acceptance test 18). wouldClose named imaps, pop3s and sieve, and
those were exactly the three that closed (LP-16).
One caveat about the method, because it nearly produced a false pass in
reverse. A published Docker port accepts connections whether or not
anything is listening in the container, so connecting proves nothing. The
first run of this script reported IMAP still open after the switch, and
that was the script being wrong, not the server. Each port now has to
speak: a TLS handshake on 993, 995 and 465, a greeting on 25.
It lives under tests/ because target/ is ignored and this is worth keeping.
It derives its own root, needs Docker and a debug build, and clears its
state directory first -- a half-bootstrapped one from an earlier run is no
longer in bootstrap mode and the recovery admin stops working.
Found while setting up the live check, which is the only place it could
have shown: every unit test passes without it.
spawn_restored_listeners re-parsed the listeners and spawned them, but
never bound their sockets. Binding is not part of parsing -- it happens in
bind_and_drop_priv, once, at startup -- so listen() would have failed on an
unbound socket and the port would have stayed shut while the policy
recorded it as reopened. LP-5 would have been a promise the server did not
keep, and the operator's only clue a log line.
bind() is now split out of bind_and_drop_priv and called on its own here.
It cannot be the whole of bind_and_drop_priv, because that also drops
privileges, which must happen once at startup and never again.
That split has a consequence worth stating: a listener on a port below 1024
cannot be bound again once privileges are gone. Ports 143 and 110 are the
realistic cases. Rather than leave such a listener parsed, spawned and
silently dead, the bind errors are read back and those listeners are
reported as needing a restart -- which is the "cannot be recreated" case
LP-5 already anticipated, and it stays saved for another try.
Re-parsing is also narrowed to the listeners being restored, so putting one
back cannot bind a port another listener already holds.
The fork had CI and nothing after it. v2026.9.20 was tagged and released
by hand, and there has never been an image: running INBUXA meant
building the tree yourself, or using install.sh to do it for you.
This adds the three workflows ihasmail already runs -- weekly release,
publish, prune.
Monday 10:07 UTC, and nothing on a quiet week. Last of the three, so
INBUXA Admin and the webmail release ahead of the server they talk to,
and staggered so a bad Monday names one repository rather than three.
The version is the difference from ihasmail. ihasmail derives its
version from the commit it builds, so its release only reads. INBUXA's
lives in the brand_version! macro, deliberately apart from Cargo.toml so
upstream's bumps merge without conflicts -- so the release writes it:
the bump is committed to main and the tag names that commit. The tree a
tag points at therefore reports the version the tag claims, which a tag
placed beside an unbumped macro cannot promise.
Both the bump and the read are scoped to the macro body and fail if they
do not match exactly once. branding.rs holds other string literals, and
a bump that silently edited one of those, or an image tagged from one,
would be worse than a run that stops.
The existing Dockerfile needs nothing: it cross-compiles from
BUILDPLATFORM and takes no arguments beyond TARGETPLATFORM, so each
architecture builds on its own native runner as ihasmail's does, without
docker-bake.hcl. `docker build --check` is clean.
Two things to expect from the first run. GHCR creates a package private
the first time even in a public repository, and no workflow can change
that, so the first image will refuse an anonymous pull until its
visibility is set by hand. And a full Rust build of this tree is long;
the per-platform GitHub Actions cache is what keeps the second one from
being just as long, and it is worth watching that it stays inside the
cache limit.
The switch is now reachable. /get and /set on a server-level singleton,
wired through jmap-proto the way inbuxa:AiLimits is: object, method names,
request and response variants, reference resolution and evaluation.
/set does not write the policy. It hands what was asked to
Server::set_protocol_policy, which applies the locks, moves the listener
objects and opens or closes their sockets, and reports what happened. So
the method cannot drift from what the switch actually does.
Two properties exist for the screen rather than the server. lockedProtocols
serves LP-21's locked set, so the selector renders SMTP and JMAP locked
from what the server says instead of a list the front end carries -- and
unlocking later needs no admin release. wouldClose answers LP-16: exactly
which listeners turning the switch on would close, by name and port, before
anything happens. It is computed against a hypothetical disabled policy, so
it reads the same whichever way the switch is set, and the registry is only
asked when the property was requested.
savedListeners, changedAt, changedBy and both of those are the server's to
say; a client that sets one gets invalidProperties naming it. closeSubmission
is different: locked, not immutable, so it is overruled rather than refused
and the response hands back what was really stored (false). JMAP already has
the place for that, the value beside an updated id.
Permissions reuse SysNetworkListenerGet and SysNetworkListenerUpdate rather
than adding to a schema-generated enum -- the same choice AiLimits made with
the classifier's. It also reads right: this takes listeners away and puts
them back, so whoever may edit a listener may turn the switch.
changedBy stores the account id, not the name, which survives a rename.
Still no screen, no sign-in refusal (LP-6) and no event (LP-8).
The join: the policy decides, features owns the listener objects,
ListenerControl owns the running sockets, and only Server has both.
Server::set_protocol_policy is what a click performs. It applies the locks
to what was asked before storing anything (LP-21), so what is recorded is
what the server allows. Closing removes each listener object and then stops
its socket; opening puts the object back and then spawns it. The order is
the point in both directions -- a socket stopped while its object remains
returns on the next restart, and a socket spawned before its object exists
has nothing to come back to.
saved_listeners is carried over from the stored policy rather than taken
from the request. A client never sets it, and a /set that omitted it would
otherwise lose the listeners still waiting to come back.
Putting a listener back has to bind a fresh socket, so it re-parses from
the registry -- the objects are already back by then -- rather than trying
to revive the saved one. Only main knows which session manager a protocol
wants, so it leaves a spawner behind at startup and spawn_listener is now
shared between that and the initial spawn. Without a spawner a restored
listener is reported as pending a restart rather than promised, which is
what the test servers will see.
A listener that cannot be put back does not stop the others and stays
saved for another try (LP-5).
Still nothing an operator can reach: no JMAP method calls this yet, and no
sign-in is refused. What it does do is close and reopen a port on a
running server, which is the part that did not exist this morning.
John, 2026-09-20: "SMTP and JMAP should be shown with the selector locked,
we want to prevent those two protocols from being shutdown for now."
The selector lists every mail protocol the server speaks, so the operator
sees the whole surface at once; SMTP and JMAP sit in it named and visibly
not switchable. JMAP was never closeable -- closing it locks everyone out
of their mail and the operator out of INBUXA Admin, with no way back but
the host -- and is now visibly so. SMTP is locked whole. LP-3 already
spared inbound on 25; this extends that to submission on 465 and 587,
which LP-1 would otherwise have closed by default.
So closeSubmission has no effect while the lock stands, and is forced to
false. A client that asks for true is not refused: the value is recorded,
overruled, and the overrule reported, because the field is specified and
the lock is meant to be temporary. is_locked() is consulted before
anything else in closes(), so no phrasing of a request reaches past it.
This costs the feature nothing. Submission's ports stay open and sign-in
over them is still refused once LP-6 lands, which is the case acceptance
test 2 already described: a mail app reaching 465 is told it cannot sign
in rather than finding nothing listening. The operator also keeps a port
they may well be forwarding, which is the LP-20 problem in miniature.
The locked set is a server constant the front ends read, not a list they
carry, so unlocking later is a server change and no admin release. The
LP-3 tests stay as they are, to keep it covered if the lock is lifted.
Recorded as LP-21, with acceptance tests 17 and 18.
LP-1 and LP-5, the registry half. close() removes every listener object
the policy closes, saving each one whole first; reopen() puts them back.
The switch removes the listener objects, not just their sockets. A stopped
socket returns on the next restart, which would reopen every port the
operator had just closed, and the operator would have no way to know. A
removed object stays removed, and a server that boots with the switch on
never spawns those listeners at all -- so there is no boot-time special
case to write or to forget.
LP-3 is decided here, on the object rather than the running socket, and
sees every address a listener binds: a submission listener that also binds
25 is inbound and stays. lmtp and http are never candidates.
A listener that cannot be put back does not stop the others; it comes back
with its reason and stays saved for another try (LP-5). A delete the
registry declines is reported as not removed, so the policy never claims a
port is closed while it is still accepting.
Stopping the running socket is still a separate step in common, which owns
the listener registry. Nothing calls any of this yet.
The server-wide legacy-protocols policy: the switch, whether submission
closes with it, the listeners taken away to honour it, and who last
changed it. Stored like inbuxa:AiLimits, as JSON in the fork's subspace,
so an unset field reads as its default and an old record still loads.
closes() is where LP-3 lives. imap, pop3 and manageSieve are named
outright; smtp is not, because an SMTP listener is inbound or submission
depending on its port and nothing else can tell them apart. A listener
bound to 25 is inbound whatever it is called, including one that also
binds 465, so it stays. http and lmtp are never candidates at all.
savedListeners keeps each listener's registry object whole rather than a
few fields of it. LP-5 promises the listeners come back exactly as they
were, and a listener carries proxy networks, TLS timeouts and socket
options that no one should have to re-derive -- a field this code has
never heard of has to survive the round trip too, and a test holds that.
The module is under security/ rather than beside the rebuilt features,
because this one is not a rebuild: upstream has nothing like it.
Still only a fact. Nothing reads this policy yet, so no port closes and
no sign-in is refused; the acting code needs the listener registry and
the config store, which live above this crate.
Left over from this morning's dependabot merges: the minor-and-patch group
freed sequoia-openpgp to use base64 0.22.1, but the lockfile still pinned
0.21.7 for it. Any cargo invocation rewrites the line, so it was showing up
as spurious drift in unrelated diffs.
No manifest changed and nothing is upgraded here; this only writes down
what cargo already resolves.
The legacy-protocols switch has to close the IMAP, POP3 and ManageSieve
ports and leave everything else accepting. The server could not do that.
Two findings from the source, both now recorded in the spec. A settings
reload never closes a port: cache/reload.rs parses the listeners only to
collect configuration errors and drops the result, and sockets are bound
once at startup through init.servers.spawn in main.rs. And there is only
one shutdown signal -- Listeners::spawn makes a single watch channel and
hands every listener a clone -- so the one thing the server could do was
stop all of them at once, port 25 included. That answers the spec's open
question 1, and the answer was neither of the two it offered.
So each listener gets its own channel. ListenerControl holds the sending
ends keyed by listener id; firing one breaks that accept loop, which drops
its TcpListener and closes the socket. The accept loop itself is unchanged
-- it already did the right thing, it just had no way to be told about one
listener. stop_matching takes a predicate and a keep list, because the
inbound listener shares its protocol with submission and telling them
apart is the caller's job (LP-3), not this registry's.
spawn_with_control is a second method rather than a change to spawn. The
registry owns the senders, so a dropped registry would stop every listener
at once; the four test callers pass no registry and keep the old shared
channel exactly as it was.
Whole-server shutdown now fires the per-listener channels too, since the
returned sender no longer reaches them.
No policy, no JMAP and no screen yet: this is only the mechanism, with
seven tests over stopping one, stopping many, sparing port 25 and sparing
submission. It closes no port on its own, and it does not touch the host's
firewall or any port-forward -- that is LP-20, and stays the operator's.
decancer 4.0 changes CuredString's Deref target from String to str. That
is all it takes to break two call sites in the classifier: .as_str() used
to resolve to String::as_str through one deref, and now resolves to the
inherent str::as_str, which is still unstable (rust-lang #130366). Stable
rustc rejects it, so the whole crate fails to compile -- the two E0658s
that are currently red on the decancer bump in PR #4.
Neither call site wanted an inherent method, only a &str. Deref coercion
gives that under either target, so dropping the .as_str() fixes 4.0 and
keeps 3.3.3 building; cargo check passes against both. The result is
identical either way, so no behaviour changes here.
Committed against 3.3.3, which is still what the lockfile pins. The bump
itself stays PR #4's to carry, and rebases onto this.
Translation::String going from Cow<'static, str> to CuredString, the other
breaking change in the 4.0 notes, touches nothing: the type appears
nowhere in the tree.
brand_version! goes to 2026.9.20 (SPEC.md 2.6: YYYY.M.D), the version this
release is tagged at. Verified from the built binary rather than the
source: --version prints "2026.9.20 (Stalwart 0.16.22)" and --help leads
with "INBUXA Server 2026.9.20 (Stalwart 0.16.22)".
install.sh still said "See https://inbuxa.org once it's up", which stopped
being true when the site went up this morning, and offered nothing but a
cargo line. It now names both ways to build, says what a server with no
configuration does, and points at the releases page and the docs.
The installer it stands in for is still unbuilt (SPEC.md 6.1), and the
script says so plainly: an installer trusted with a mail host is not a
thing to improvise, so it declines rather than half-doing one.
README: inbuxa.org is up, so stop saying it is not, and link the docs.
