Adding custom milter to master.cf

[ginkel]

Hi there,

how would I add a custom milter to master.cf? I read about postfix-master.cf and that it is not appended literally. How would I append the following (still untested) snippet?

opengpg-filter   unix  -       n       n       -       10      pipe
  flags=Rq user=postfix argv=/usr/bin/python3 /tmp/docker-mailserver/opengpg-milter.py

Thanks,
Thilo

postconf -M 'opengpg-filter unix - n n - 10 pipe flags=Rq user=postfix argv=/usr/bin/python3 /tmp/docker-mailserver/opengpg-milter.py'

See the workaround section at the end of this comment for reference of adding a user-patches.sh to your config volume. That will run the command when starting a new DMS container instance.

It should add the line to /etc/postfix/master.cf for you. postfix-master.cf is only used to override settings.
