Should be fine. Actually, we don't allow direct connections to SMTP on that
server. We have another SMTP server (which happens to be our virus scanning
server, from Trend Micro) that acts as the primary SMTP gateway. Port 25 is
the only open port on that machine. The address is also translated (more for
management than for security). VirusWall passes on e-mail to the Exchange or
other e-mail servers after it finishes scanning messages for viruses.
