I have an Enterprise server configured with several domains, ver 5.62. I have a second box with 8.52 running and configured identical to the first box. I would like a copy of all incoming mail to the old server forwarded to the new server.
I have tried the MESnoop utility but it will not 'run' on the old server, ie the process shows up in task manager but I never get a window to configure it. It seems like I will have to hook into the MTA somehow and create a copy and forward it to the new ip.
My reasoning is I would like to verify proper operation of the new server for a while before springing it on our customer base. Has anyone been able to accomplish this?
