postfix mail server with configurable hostname and trusted hosts and proper shutdown handling
By default, connected rfc1918 networks are detected and allowed. Local networks (127.0.0.1, ::1) are also allowed.
Postfix logs to a syslog server. Unless indicated, no syslog server is configured or started started. (the phusion baseimage does start a syslog server).
For simplicity, you can bind-mount the one on the host using -v /dev/log:/dev/log
/var/spool/postfix is the spool directory. Its also where postfix chroots to by default./etc/postfix is the configuation directoryYou can customize the image behavior using environmental variables or entrypoint arguments.
