set Joomla server to send email
I have installed Joomla on an Ubuntu 10.04 Server pc. The Ubuntu server is connected to my Novell NetWare network via static IP. I need the Ubuntu server to send mail to my mail server through smtp, my entire network has static IP's. The Ubuntu server does not need to receive mail only send, I have found that I could try use sendmail, postfix or exim4. I tried Exim4 but I am battling with the setup. For my situation what would be the best to use? What config's are most important to set?
