Daemon mode, although I was (am) not aware of any glaring insecurities...
The machine has nobody but administrators logging on, which may be why I
wasn't worried about local exploits.

TBH, this machine does RADIUS, SMTP/POP3/IMAP, DNS and a little bit of HTTP
(internal only). By far, the biggest strain on the system is the virus
scanning. If you're using the 'spawn the full SA scanner per email' method
to spam scan I could see a serious increase in processor load, though.
