Hi Mark,

Thanks for your reply.

After adding

virtual_alias_domains = pgsql:/etc/postfix/pgsql_virtual_domains_maps.cf

I received the following bouce back :

User unknown in virtual alias table

and the following warning in the log file :

warning: do not list domain XXX.com in BOTH virtual_alias_domains and virtual_mailbox_domains

Virtual mailboxes are working, just not the forwarding to mailman. Here is the output for postconf -n

I am trying to setup mailman on my linux server running postfix and

It isn't necessary to include hash:/var/lib/mailman/data/aliases in
alias_database. It only says that /var/lib/mailman/data/aliases.db will
be updated if you issue a "newaliases" or "sendmail -bi" command which
isn't needed as Mailman issues the appropriate "postalias" command
whenever it updates /var/lib/mailman/data/aliases.

alias_maps = hash:/etc/mail/aliases, hash:/var/lib/mailman/data/aliases

virtual_alias_maps = hash:/var/lib/mailman/data/virtual-mailman,

You have hash:/var/lib/mailman/data/virtual-mailman listed twice.

Do you have "XXX.com" in virtual_alias_domains? You probably need this
unless "XXX.com" is in virtual_mailbox_domains.

Ran genaliases to create /var/lib/mailman/data/aliases and
/var/lib/mailman/data/virtual-mailman which seem to contain the correct

However emails to mailmain@domain and list-staff@domain are bounced with
unknown user:

Since postfix/virtual is doing the bouncing I am suspected that the
mapping (virtual-mailman) was picked up, and that i cannot find the
mapping in aliases, but I could be wrong here.

Postfix virtual is the delivery agent for virtual_mailbox_domains, not

It is possible to use virtual_alias_maps to map addresses that are in a
virtual_mailbox_domain, see
<http://www.postfix.org/VIRTUAL_README.html#virtual_mailbox>, so I'm not
sure why this isn't working, but if you still have issues after reading
the above link, post the output from 'postconf -n'.
