If a user install and configure mailman correctly but uses courier MTA, mailman does not work. In the mail log there is this error: [Mailman mail-wrapper] Group mismatch error. Mailman expected the mail_wrapper script to be executed as group "mailman", but_the system's mail server executed the mail script as_group "mail". Try tweaking the mail server to run the_script as group "mailman", or re-run configure, _providing the command line option `--with-mail-gid=mail' This is because courier tries to execute the script with the mail GID, the only solution i found was changing the mail gid in mailman ebuild. It could be useful that the ebuild would detect courier and change the gid in the proper way. Regards Reproducible: Always Steps to Reproduce: 1. Install courier MTA 2. Install Mailman 3. Configure a Mailing List Actual Results:
same GID issue. *** This bug has been marked as a duplicate of 45439 ***
