Currently we have sbs2003 connected to a network with 2 gateways (different isp's)
The purpose of this is to remove all email traffic away from the main gateway. Currently to do this I have created a smart connector to the second gateways smtp server and added a route to the second gateways smtp server to force it to go out through the second gateway.
This works ok however for some reason mail gets stuck in the smtp queue (isp rejecting certain messages or similar) and we need to flick over to dns to clear the queue and then go back to the smart connector.
Is there a way I can enable dns instead of the smart connector and force any smtp traffic to route out the second gateway??
Im fairly new to microsofts routing but I can add and remove persistent ip routes. Is it possible to add a route to a gateway by port??
Cheers for the info...
