I'm not a Postfix expert, but the following entry in your configuration 
file is problematic:

virtual_alias_maps = hash:/var/lib/mailman/data/virtual-mailman, 
hash:/var/lib/mailman/data/aliases, 
mysql:/etc/postfix/virtual/aliases.cf

I can't comment on your database setup, but your Mailman aliases should 
not be here, they should be in alias_maps.  And in fact they are also.  So 
I'm sure this doesn't help your situation.
