Not having used Mailman in a Postfix setup before, I can only speculate a bit. From what I can tell, all your mail is delivering through the dovecot transport and no transport designation is being performed for the mailman address aliases. I'm not familiar with a virtual_email2email configuration option. Do your list addresses map to anything in your virtual_mailbox_maps configuration? That is, do they map to a real address defined in virtual_mailbox_maps?
For me, aliases in virtual_alias_maps map to real addresses in virtual_mailbox_maps, and then map to transports in transport_maps where they get passed off to the appropriate handler. I would imagine the mailman addresses need to be mapped in virtual_mailbox_maps and handed off via transport_maps. Also, have you tried raising the debug level to diagnose the hand-off in logs?
