We're sorry, we hit a bug!

Please inform the webmaster for this site of this problem. Printing of traceback and other system information has been explicitly inhibited, but the webmaster can find this information in the Mailman error logs.

Please tell me where to find the error logs, so i can post them here.

The Mailman logs could be anywhere. The default location if you installed from source is /usr/local/mailman/logs/. Try "locate mailman" to find your Mailman installation. Please post the complete error information from Mailman's error log. Without that, we don't have a clue.

" RuntimeError: command failed: /usr/sbin/postalias /etc/mailman/aliases (status: 1, Operation not permitted)"
in the logs seems to be the culprit but need you...

[Mark Sapiro (msapiro)]

The issue in comment #4 could be due to several things.

The /usr/lib/mailman/cgi-bin/create wrapper should be Mailman's group and SETGID. Is this true? If so, the process runs as the web server user with the Mailman group as it's effective group, and this process can't do "/usr/sbin/postalias /etc/mailman/aliases". This could be a permissions issue or a SELinux issue.

Can you run the command manually as the Mailman user?

Also, please see the FAQ at <http://wiki.list.org/x/OIDD>.
