My first test was with Debian unstable, but with a mail server, I think
I want to run Debian stable. That's why I wrote a script that will
automatically install SA-Exim. Here it is. I don't know why, but I had
to fish out the dependencies for SpamAssassin for the whole thing to go
automatic.

Description: Use spamAssassin at SMTP time with the Exim v4 MTA
 SA-Exim lets you use spamAssassin at SMTP time with the Exim
 v4 MTA, which enables you to do many things with incoming Emails,
 including refusing them before they come in, or even teergrubing the
 sender (i.e. slowing him down, by tying his resources)
 .
