mailman aliases : user unknown

I am using a ispconfig 3.0.4 server and I installed mailman at the time of install.

I can create and delete mailing lists via the panel, and I can log in to administer them via

the problem is that I can't see how the /etc/mailman/aliases file is linked to postfix. When I send an email to my created lists, I get a "user unknown" email returned.

I am running Centos 6.3. Any tips how I can get postfix to recognize the mailman aliases for each list?

there is also /etc/mailman/virtual-mailman

do I have to manually edit postfix or some other config file to have them included in ISPC3?

Did you install mailman as described in the installation guide?

yes I installed the mailman package by following the perfect server centos6.3 document.

what is crazy is that ispconfig3 does allow me in the panel to create/delete the mailing lists, I can access the admin pages and configure the lists, add moderators and addresses and whatnot, the broken link is between the mailman alias file and postfix. when an email is sent to the list, it is rejected as user unknown.

here is a postfix -n. is there anything blatantly wrong? I see no mention of the mailman alias files therefore question how this can work.

so I manually modified, and made some progress in getting mailman to handle inbound mail to its addresses;


alias_maps = hash:/etc/aliases, hash:/etc/mailman/aliases
virtual_alias_maps = proxy:mysql:/etc/postfix/, mysql:/etc/postfix/, hash:/etc/mailman/virtual-mailman

will this modification survive upgrades to ispconfig? is there a different way postfix is informed of the list aliases created by mailman?
