[Mailman-Users] Problem setting up Mailman on Gentoo

[Jeff D]

I use sendmail, but I always have had to modify the ebuild file for 
Mailman to fix "MAILGID" to be the group that smrsh executes Mailman as 
(in my case "12" or "mail"). You probably need to do the same.

Make a copy of the Mailman ebuild in your PORTAGE_OVERLAY directory, 
modify the ebuild with MAILGID set to the correct group and then 'emerge' 
mailman again.
