So now it seems you are saying you need to make the postfix on the
gateway server aware of what addresses to handle.

You can use Mailman's data/virtual-mailman.db directly in
relay_recipient_maps on the gateway server.

You could create a script on the Mailman server containing

#!/bin/sh
/usr/sbin/postmap $1

followed by an rsync or whatever to update the file on the gateway

and put

POSTFIX_MAP_CMD = '/path/to/script'

in mm_cfg.py to keep the files in sync.
