[Exim] PHPMailer

Hi there guys.

Just trying to sort out my mail. And a few scripts [php] I got off the
net.
This is the Error that I get.


Message could not be sent.
Mailer Error: SMTP Error: Could not connect to SMTP host.

Can someone assist me in getting the above mentioned package installed.
Or is this a problem with exim.?

Regards
Marcus
