Linux Mail Servers?

Whats up guys. Just curiouse to kno if there are any good Linux mail server progs out there. I am currently running Fedoa Core 3 and cannot get sendmail to work properly. To much trouble. I have head about Extremail, and downloaded some RPM's for that, but have not tried it out yet. Just seeing if any information can be provided before I dive into the Fedora Forums yuckkkkkkkkkk ..

Thanks!
