I',m add a new user manually... with path /var/www/virtual/mailman. Inside I make a default page... anyone... but, to access to Mailman web config... I do:
http://www.domain.com/mailman/create or /listinfo.... or ...
The permissions of directori /usr/lib/cgi-bin/mailman/ is root.list
Think that you make a new mailman.conf without SUEXEC... for this workly all... but apache write in iscpc.conf *.domain.com... you have delete of template this option...
in /etc/postfix/main.cf, I add to end file this: relay_domains = listas.domain.com
