Sorry for the late reply. I was out for a few days.

I basically do things the same way John talks about as far as upgrading.

I also control the MTA (postfix here) with 2 separate init scripts, one
for incoming and one for outgoing.

I start MailScanner with check_mailscanner via cron:
@reboot                   [ -x /opt/MailScanner/bin/check_mailscanner ] && /opt/MailScanner/bin/check_mailscanner >/dev/null 2>&1
0,20,40 * *    *     *    [ -x /opt/MailScanner/bin/check_mailscanner ] && /opt/MailScanner/bin/check_mailscanner >/dev/null 2>&1

I don't have a clean way to automatically shut down MailScanner before
power down/reboot. I don't need that very often. The last time (also the
first time) I needed to do that I just got the pids manually from
check_mailscanner and killed the parent before shutting down.

I'm probably going to write or borrow a simple init script to do that
piece eventually.
