postmap /etc/mailman/virtual-mailman


postalias /etc/mailman/aliases

assuming those are the correct paths, and run them both as the 'mailman'
user. In any case, the resultant virtual-mailman.db and aliases.db
should be both user and group 'mailman' or whatever the mailman
user/group is on your system.

Note that the command is postmap for the virtual maps and postalias for
the aliases;

If that doesn't fix it, post the output from 'postconf -n' and the
postfix log messages for a failed delivery.
