Openwebmail is a mail server that runs from the web. It requires suidperl. I have installed the suidperl rpm and suid shows up in /usr/bin but if try to access openwebmail from the web i get internal server error. Inside the http access_error logs it says can't set suid. Is this not a perl problem? If there is something in apache that i am forgetting to enable or configure can you explain where to look to how to do that?
I'm not familiar with Openwebmail nor with suidperl. If I were you I would join the fedora-list mailing list, and/or join the #fedora IRC chat on freenode.net and ask your questions there. Good luck - sorry I can't be more help.
