We just upgraded 2 MX2000 to MX 2003. One at Site1 "site1.overhere.all.com" & the other at Site2 "site2.overhere.all.com". They are a child domain of "all.com"
Mail flows from Parent to Site1 & from Site1 gets routed to Site2.
The build wasn't too bad (thanks to Sembee), but I have problems stopping the services. Site1's old MX is up but has all MX services & SMTP disabled. When I try to do that for Site2, all mail gets queued at Site1. This is really bizarre.
If I turn off the services on the old MX at Site - I get this problems:
1. No mail between Site1 & Site2 (should I use smart host or not? - how do I config it ?)
2. All mail for Site1 gets queued at Site2
