Mailman + Postfix

[Robert Bell]

I installed Mailman 2.1.5 on FC4 tonight and followed the directions on 
their website. It seems to have gone well with the exception that the 
CGI doesn't generate the aliases, I have to do that by hand. In the 
mailman error log I see this.  How can I tell why postalias is failing?

Aug 23 23:06:13 2005 (27677) command failed: /usr/sbin/postalias 
/etc/mailman/aliases (status: 1, Operation not permitted)
