Please post the output from 'postconf -n'. Also specific Postfix log
messages might be helpful. as well as a sample of the content of

If XXX.com is a virtual_alias_domain or a virtual_mailbox_domain, it
shouldn't be in my_destination.

If you have XXX.com in virtual_alias_domains and your list addresses are
mapped from lisname at XXX.com to listname in virtual-mailman, it should
work. What is the Postfix error message in this case?
