Usage (as of 2024)

Intro

• Postfix can be started using "/usr/sbin/postfix start-fg"
• Logging is already configured for stdout

Next todos

TODO Add simple authentication support

• so we can be used as a smarthost
• might require dovecot for sasl auth

Stuff to do (before 2024)

PROGRESS Add smtp support (postfix?)

PROGRESS Add imap support

• maybe later?

PROGRESS Define where/how to save mails

• /data would be fitting
• database as an option - that might require its own pvc

PROGRESS Add db support (?) or not?

• all file based could be very easy
• restarts are usually fine
• requires dovecot in same containerx

TODO Define deployment requirements (such as SPF/DKIM etc)

DONE add stdout logging

CLOSED: [2024-10-05 Sat 14:37]

Logging to stdout is useful when Postfix runs in a container, as it eliminates a syslogd dependency.

Add the following line to master.cf if not already present (note: there must be no whitespace at the start of the line):

postlog unix-dgram n - n - 1 postlogd

Note: the service type "unix-dgram" was introduced with Postfix 3.4. Remove the above line before backing out to an older Postfix version.

Configure main.cf with "maillog_file = /dev/stdout".

Start Postfix with "postfix start-fg".

TODO Check EAI support
