Export matched each item against the target and then skipped it, so a second run -- the usual final pass of a cutover -- never carried anything that had changed at the source since the first: read and flagged state, moves between folders, edited contacts, events and Sieve scripts. It reported them as skipped and exited 0, while the usage guide said matched items were updated. Matched items are now updated, with one batched /set per type: - Email: keywords are set to the archive's, added and removed, compared case-insensitively. Memberships of folders this run migrated are added and removed to match; folders that exist only on the target are left alone, and a message is never left in no folder. Properties the server did not report are not touched. - Contacts and events: when both copies carry `updated`, the archive's is written only if it is newer; otherwise each property the archive writes is compared, and those that differ are sent whole. - Sieve scripts: the target's copy is downloaded and compared byte for byte, and replaced with the archive's when it differs. Updated items are counted as `updated`; unchanged ones stay `skipped`. The usage guide now describes this.

Note
Development happens on git.coffeylabs.org/inbuxa/inbuxa-migrate; the copy on GitHub is a read-only mirror. Report issues at git.coffeylabs.org/inbuxa/inbuxa-migrate/issues, and join discussions at community.coffeylabs.org.
One program that moves an account into inbuxa: its mail, calendars, contacts, identities, Sieve scripts and files.
inbuxa-migrate import imap … alice.sqlite an account into an archive
inbuxa-migrate inspect alice.sqlite what landed
inbuxa-migrate export … alice.sqlite the archive into inbuxa
Between the two sides sits an archive: one SQLite file holding one account.
import fills it from the old server; export writes it into the new one.
Import and export never talk to each other, only to the archive, so the old
server can be gone before the new one exists.
Both commands converge. An interrupted run picks up where it stopped, and a
later import into the same archive adds what arrived since. Every command
takes --dry-run and then only reports the plan. inspect reads an archive
and changes nothing.
The archive is also a backup. Import on a schedule, keep the file, and
restore it later with export. An archive remembers which account filled it
and refuses a different one unless told otherwise.
Export speaks JMAP only. It writes into inbuxa, or into any JMAP server that advertises the types being written. The full command reference is in docs/usage.md.
Sources
- JMAP -- any JMAP account, including an inbuxa or Stalwart server.
- IMAP -- mail only. Folders are chosen by name or by pattern.
- CalDAV, CardDAV -- calendars and events, address books and contacts.
- WebDAV -- a plain file collection, kept as a file tree.
- ManageSieve -- Sieve scripts only, with the active one recorded.
- Maildir -- a local Maildir++ tree. No network.
- Google Takeout -- the
.mbox,.icsand.vcffiles in a Takeout export, or in any directory tree laid out that way. - Exchange Server -- an on-premises mailbox, through EWS.
- Exchange Online -- through Microsoft Graph. EWS is being retired in Exchange Online: blocked from October 1, 2026 unless an administrator allows the client, and switched off on April 1, 2027. Public folders are only reachable through EWS.
Credentials
Secrets are read from the environment, or asked for at a prompt:
INBUXA_MIGRATE_PASSWORD a password for --auth-basic
INBUXA_MIGRATE_TOKEN a bearer token for --auth-bearer
INBUXA_MIGRATE_EWS_CLIENT_SECRET the OAuth client secret for app-only EWS
INBUXA_MIGRATE_GRAPH_TOKEN a Microsoft Graph access token
The command line takes them too, but a secret there ends up in the shell's history and in the process list. Use the environment or the prompt.
Installing
Linux, on amd64 or arm64. Each release carries one archive per architecture
and a SHA256SUMS file:
base=https://git.coffeylabs.org/inbuxa/inbuxa-migrate/releases/latest/download
curl -fLO "$base/inbuxa-migrate-linux-amd64.tar.gz"
curl -fLO "$base/SHA256SUMS"
sha256sum --check --ignore-missing SHA256SUMS
tar -xzf inbuxa-migrate-linux-amd64.tar.gz
./inbuxa-migrate --version
On arm64, fetch inbuxa-migrate-linux-arm64.tar.gz instead. The binary is
the whole program; put it anywhere on the path.
Building and testing
cargo build --release the binary is target/release/inbuxa-migrate
cargo test the default suite
The default suite needs no network and no Docker. Unit tests and scripted mocks stand in for JMAP, DAV, EWS and Graph servers.
The live tests are marked #[ignore]. Each boots a throwaway container --
Stalwart, Dovecot, Cyrus, Radicale, Baikal or Apache mod_dav -- so they
need a working Docker daemon. Run them one binary at a time, and always with
one test thread:
cargo test --test sync_jmap -- --ignored --test-threads=1
cargo test --test integration_dovecot -- --ignored --test-threads=1
The tests in a binary share one container and one disposable domain, so a second thread would trip over the first. docs/usage.md lists every live test binary.
