As you have discovered, Mailman/Postfix integration with Postfix
virtual domains uses virtual alias domains, not virtual mailbox
domains. If you want/need to use virtual mailbox domains, I'm afraid
at this point you're on your own.

Mailman supports two delivery methods. The normal method is delivery to
a command via a pipe using aliases or some programmatic transport in
some MTAs which support it. This is not delivery to a mailbox, so
virtual mailbox domains will not support this.

The other method is delivery to a MAILDIR. See the comments both before
and after the line "USE_MAILDIR = No" in Defaults.py. It is possible
to use MAILDIR delivery for addresses in virtual mailbox maps, so you
can probably set this up, but you would have to modify
Mailman/MTA/Postfix.py to generate the proper maps or maintain them
