What mail server do you use? I am researching on what I want to use with CPanel, Spam Assasin and WHMAutopliot. I have received recommendations from friends from Exim to Qmail. What do you recommend? Vices? Thanks!

You don't really have a choice with cPanel, as it comes with Exim by default. You may be able to mod QMail to work with cpanel but I haven't heard of it being done.

Thank you for your reply. I searched all over CPanel's site looking for a PREFERED mail server but couldn't find anything. I have searched the message boards to see how stable Ensim is, I see problems but I guess they don't compare to the security problems found in sendmail.
