The ihasmail default was a pin that went stale within days, and ihasmail
keeps ten releases' images, so an old default would in time stop pulling.
With no --ihasmail-image the tool now pulls :latest before asking, reads the
version the image carries, confirms the dated tag is the same image, and
writes that tag into compose.yaml (or the digest, if there is no such tag).
Stalwart and Caddy stay pinned. A weekly end-to-end run against the newest
release, three hours after ihasmail publishes, is what keeps it safe.
The same licence as ihasmail, which this tool deploys. The network clause
is the part that matters for a deploy tool: a modified copy offered as a
hosted service that deploys for other people has to make its source
available to them, which GPL would not require. Running the tool for your
own host is unaffected.
v2026.9.13 was released under GPL-3.0-or-later and stays so; this applies
from the next release.
scripts/build-release.sh builds reproducible linux/amd64 and linux/arm64
archives with SHA256SUMS; the release workflow runs it on a v* tag after
vet, tests and govulncheck, and publishes the release. The README now
covers what the tool is, what it does step by step, why each decision is
made, how to deploy and run a mail host, the security model, and
troubleshooting. -h exits 0.
deploy stands up Stalwart 0.16, ihasmail and (for a mail host) Caddy as a
compose project: completes Stalwart's bootstrap over x:Bootstrap, links
ihasmail over the private network, requests certificates for both Caddy
(TLS-ALPN-01) and Stalwart (HTTP-01 through Caddy), makes the auto-ban safe
behind the proxy, and proves the link by signing in through the webmail.
--local gives a loopback-only pair. certs retries Stalwart's certificate;
destroy removes a deployment.
e2e/public.sh runs the whole mail-host path against Pebble with no
internet involved.
