Something is wrong here because if everything is properly configured per
the FAQ at <http://wiki.list.org/x/10715238> the transport (relay)
should be 'local' not 'dovecot'

Again, if things are properly configured per the FAQ at
<http://wiki.list.org/x/10715238>, virtual-mailman is only used to build
transport-mailman and only aliases and transport-mailman are used by
postfix for Mailman mail.

postfix-to-mailman.py is incompatible with this and definitely won't
work well in a multi-domain environment. See the FAQ at

You probably can't make it work in your environment.

For further help, please post the output from 'postconf -n' and the
contents of /etc/postfix/master.cf.
