[ale] Exim relay setup

[James P. Kinney III]

I will echo Jenn's sugestion on MailScanner. It will also scan mail for
virus bugs if an anti-virus it knows about is available. I use f-prot
(free for personal workstation use, cheap for small office mailserver
use) www.f-prot.com.  MailScanner is much easier to set up than than any
of the other systems. It will integrate spamassassin processing as well.
Great tool.
