You seem to have a basic grasp of the real issues. You can use that

I'm surprised that "postconf -n" still lists a this parameter,

This is documented in the access(5) manual. You can limit queries
performed by using %u and %d to match local-parts and domain-parts
respectively.

Yes, that is a lot of stuff to cover. Mail admin is not for the faint
of heart. :) Good luck.

.
Best practice is to separate submission from the MX mail on port 25.
Users should not (and in many cases, cannot) use port 25 for sending
mail from their MUAs. With " -o syslog_name=postfix/submission" on
your submission smtpd command in master.cf, you can tell at a glance
that it was a user (or attacker) on 587.

Then the unknown recipient rejection, which happens in
smtpd_recipient_restrictions, will be subject to defer_if_reject.

Offlist GMX mail is seen only if "/dev/rob0" is in the Subject:
_maps file. That's really all I can guess. But
that should have given you warnings in the logs, so it's strange you
didn't see those when you retrieved the above lines.

that at the TOP it says it is not relevant for

that page.
Also, the Dovecot wiki link is only for Dovecot 1.x, not the best
