This is more secure, because you don't need to allow any connection
from DMZ to your LAN. If you forward all the mail from DMZ to your LAN by
SMTP, you have to allow incoming SMTP connection from Mail Relay to Exchange
that recides in LAN, which is potentialy more dangerous than alowing only
POP3 from LAN to Linux Mail Relay..

No. I keep a single account in Linux, which recieves all the mail
for domain, and Popbeamer (
http://www.dataenter.co.at/products/popbeamer.htm , 129$) or similar Windows
product can routes them to my Exchange users using POP3.

Probably not MTA of Exchange.
