hello, 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 http://domain.name/cgi-bin/mailman/admin/ 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?
