It's clearly wrong to have the duplicate aliases defined. I went back to
see where the original "mailman: postmaster" aliases came from because
our mailman rpm does not create these. In fact, I'm pretty sure these
aliases are from a much earlier version of mailman (2.0.x?). It turns
out that the "setup" rpm which is responsible for installing core files
installs a default version of /etc/aliases which include these
deprecated mailman aliases. I have filed a bug report against setup so
these aliases are not created when the system is first setup. This is
the bugzilla.

However, I'm not sure I can explain the behavior you're seeing, but here
is the bottom line, the mailman:postmaster and mailman-owner:mailman
should be deleted from your aliases file, the aliases that pipe
into /var/mailman/mail/mailman are the ones you want to keep. You didn't
say which MTA you were using, I assume its sendmail. When you were
experimenting did you regenerate your aliases and restart sendmail? In
any event make sure you remember to do that after you delete the bogus
aliases.

Although on my test machines I have the duplicate bogus mailman aliases
as a result of the setup rpm I've never had a problem which is why I
probably never noticed this. However, I use postfix as my MTA which
might overwrite the duplicate alias with the 2nd correct version thus
masking the problem, but thats just a theory.

If after you delete the bogus aliases and rebuild the aliases and
restart your MTA you're still having problems let me know.
