Thanks to Dan' suggestions I've fixed the perm error. I have a different MTA problem now. When I try to subscribe to the list, or send an email to the list I get...nothing. No email makes it trough the list, and I also get no subscription conformation from the list. Python 2.3.5, Mailman 2.1.5, Postfix 2.1.5, Apache 2.0.54
