The setup rpm installs the /etc/aliases file with the following entries # mailman aliases mailman: postmaster mailman-owner: mailman These aliases conflict with the aliases that the 2.1.5 version of mailman creates. I believe the above aliases were for the 2.0.x versions of mailman. The mailman package should manage its own aliases. Can we please remove these from setup? I filed this against Fedora, but I think this is true for all distributions.
Hm, those are in the original import of the file from January 2004. I wonder how far back they date. For RHEL 3 sendmail would have to be fixed. Fixed in 2.5.43-1. Not fixing for RHEL 4 for now...
