I recently added a new exchange server into an environment with an existing exchange server with plans to decommission the old server. when i setup the server i had an issue with mail routing internally so i created 2 separate routing groups and had them point to each other, which was successful. It then came time to stop the services on the old server so we could see if there was any issues. I also moved the old server that was in a routing group to the routing group of the new server which automatically put it as a member. since this i get mail that backs up in the default smtp virtual server queue of the old server.
My question is should i stop the smtp virtual service on the old server? I"ve still got the relay info on the old server as well. Would removing that make a difference? I can't find a lot of documentation on this that relates to the issue that I"m having. I enabled logging on the transport level and receive a lot of event id: 984.
Thanks for the help on this.
