xomoxcc/postfix-pgsql repository overview
postfix-pgsql
Debian trixie with postfix, postfix-pgsql, postfix-policyd-spf-python and tini. The image ships only the binaries: main.cf, master.cf and the pgsql map files are mounted by the deployment. Built for a Kubernetes mail pod next to a Dovecot container (LMTP and SASL over unix sockets in a shared volume), but nothing in it is Kubernetes-specific.
Entrypoint
postfix check, then postfix start-fg under tini. When main.cf sets maillog_file, a background loop rotates it daily with postfix logrotate followed by postfix reload.
Mounts
