bramfoxie/postfix repository overview

Postfix⁠ MTA built from Debian packages on debian:trixie-slim, with postfix-mysql for virtual maps and a submission service that inherits the global smtpd_milters (rspamd does DKIM signing + scanning). Part of the layivo mail stack.

⁠Tags

3.10.5, latest — the tag is the Postfix version. Pin a version for production.

⁠Run

Not standalone — expects MySQL maps, TLS and a milter (rspamd) alongside it. The entrypoint adjusts master.cf and runs postfix start-fg.

services:
  postfix:
    image: bramfoxie/postfix:3.10.5
    depends_on: [mysql, dovecot]

Exposes SMTP (25) and submission (587); set smtpd_milters in your main.cf (e.g. inet:rspamd:11332) — submission inherits it for outbound DKIM signing.
