On this screen (the full screen displays once the Status box is checked), you can configure the SMTP proxy and the Virus
Protection function. The SMTP proxy acts as an email relay. It accepts email for your Internet domains and passes them on
to your internal email distribution system. This can be accomplished via a Microsoft Exchange Server, for example. Emails
are transparently scanned for known viruses and other harmful content.
The SMTP proxy also acts as a gateway for outgoing mail, thus taking over the job of email distribution from your internal
email system.
Rules and Suggestions for Using SMTP Proxy
• For SMTP, a valid name server (DNS) must be enabled. The RouteFinder sends notifications to the administrator
even if SMTP is disabled. The RouteFinder processes up to 25 incoming SMTP connections simultaneously
preventing Denial of Service (DoS) attacks. The 26th incoming connection is not accepted.
