company exchange server & exim best practices.

[James Dinkel]

We use a Postfix server set up as an smtp relay that also filters all
messages going through it for spam and viruses.  There is a very thorough
guide here:
http://crunchbanglinux.org/wiki/howto/email_spam_and_virus_filter

It's actually for another Debian-derived distro called crunchbang, but I
don't see anything that shouldn't work equally on Ubuntu.  This will "push"
email to your Exchange server via smtp so be sure your Exchange server is
set to accept smtp messages (just in case it had been changed when you set
it up to pull messages via pop3).
