Mailman 2.1 under Shrike (RedHat 9) seems to be having some problems. I just did an install, and programs like ./check_perms and ./mailmanctl under /var/mailman/bin give an error: Traceback (most recent call last): File "/var/mailman/bin/mailmanctl", line 524, in ? main() File "/var/mailman/bin/mailmanctl", line 319, in main check_privs() File "/var/mailman/bin/mailmanctl", line 274, in check_privs gid = grp.getgrnam(mm_cfg.MAILMAN_GROUP)[2] KeyError: getgrnam(): name not found The fix is to edit the mm_cfg.py in /var/mailman/Mailman and manually set the MAILMAN_USER and MAILMAN_GROUP variables to 'mailman'. There is already a MAILMAN_UID and MAILMAN_GID set, but it seems that those two scripts (of which mailmanctl is very important) use MAILMAN_USER/_GROUP instead... Since RedHat intentionally sets the MAILMAN_UID and _GID, I imagine that it's up to them to also set the MAILMAN_USER and _GROUP variables, instead of the mailman people... (if I'm wrong, let me know, and I'll send this to their lists instead). I did a completely clean install on a test machine, wiped the HDs and all. Python was working ok, and mailman would receive mail, but server-side configuration was having problems...
