Exchange SMTP gateways routing users
Posted on 2004-04-16
i have to put an exchange server 2000 on the internet as a gateway SMTP server. this server is going to forward mail into the exchange server behind the firewall. what i would like to do is add an antispam server (Windows 200 SMTP) in the middle and forward mail for specific users only from the gateway through the antispam server. all other users will go directly to the exchange server behind the firewall. i have done this before but have used Sendmail as the gateway (it has an alias table to route certain users based on their smtp address). the reason why i am using the exchange server as the SMTP gateway is licensing issues with antivirus. i want to scan the viruses on the SMTP servers and the exchange server.
does anyone know a way exchange can do this with active directory?
i have seen MS KB 251124 (for 5.5), this is what i need to do in Exchange 2000. i have never deployed exchange servers as SMTP gateways before, i have only used either windows SMTP or sendmail.
