Proxy > SMTP Proxy

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.

How the SMTP Proxy Works

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 26

incoming connection is

not accepted.
