To send the test message I sshd into my box as user, su - to root, and did:
# /usr/lib/mailman/mail/mailman post test
Group mismatch error. Mailman expected the mail wrapper script to be
executed as one of the following groups:
[mail, postfix, mailman, nobody, daemon],
but the system's mail server executed the mail script as group: "root".
Try tweaking the mail server to run the script as one of these groups:
[mail, postfix, mailman, nobody, daemon],
or re-run configure providing the command line option:
'--with-mail-gid=root'.

I then use mutt (still as root) to send an email and this is what I see in /var/log/maillog

Finally I exit root and go back to being a user and I do:
/usr/lib/mailman/mail/mailman post test
Group mismatch error. Mailman expected the mail wrapper script to be
executed as one of the following groups:
[mail, postfix, mailman, nobody, daemon],
but the system's mail server executed the mail script as group: "user".
Try tweaking the mail server to run the script as one of these groups:
[mail, postfix, mailman, nobody, daemon],
or re-run configure providing the command line option:
'--with-mail-gid=user'.
