Do you have your domain in either virtual_alias_domains or 
virtual_mailbox_domains, or mentioned in a file/resource pointed at by 
either virtual_alias_maps or virtual_mailbox_maps?

If Postfix doesn't think your domain is virtual, it won't look in 
virtual_alias_maps for the address.

The config you recently posted seemed a bit mixed up, with hosts/domains 
mentioned in multiple configuration variables.  As a general rule, a 
domain should only be mentioned once in any of mydestinations 
(locally-deliverable mail), virtual_*_domains (other hosted domains that 
are not local) and relay_domains (domains you relay somewhere else).

I think that perhaps you don't have a clear understanding of Postfix 
address classes and what each is used for.  I recommend reading 
http://www.postfix.org/ADDRESS_CLASS_README.html

If your Mailman domain has no mailboxes, you can put it in either 
virtual_alias_domains or in a virtual_alias_maps file.  If you want 
mailboxes too, use the virtual_mailbox_* equivalents (I use this for 
everything personally).

HTH,
Geoff.
