From Bugzilla Helper: User-Agent: Mozilla/5.0 (compatible; Konqueror/3.0.0-10; Linux; i686) Description of problem: Mailman as deliverd with RHL 7.x is apparently compiled --with-mail-gid='mail' which probably works with Sendmail. However, when using Postfix as the MTA, that configuration of Mailman won't work. Possible fixes: compile Postfix to use gid 'mail' or split mailman into mailman-core, mailman-sendmail, and mailman-postfix. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Install RHL with Postfix as MTA instead of Sendmail 2. Install Mailman binary RPM 3. Attempt to make Mailman work Actual Results: Attempts to send mail to a Mailman-managed list return the well-known gid mismatch error. Expected Results: Should have worked without incident Additional info: This problem can be resolved by compiling Mailman from SRPM with --with-mail-gid='mailman', but that presupposes that gcc and supporting packages have been installed. Not necessarily the case on a stripped-down single-purpose server. Plus, it shouldn't be necessary for the user to recompile.

This is fixed in RHL 8.0 / 9, isn't it?
Actually I don't think it is if I understand the issue. I believe that postfix runs as the user/group 'postfix' and this is not in the list of mail users in the mailman spec file. Adding it would be trivial.
added postfix to list of groups, time to close this out, should be in mailman-2.1.2-*
