I have three exchange 2010 servers:
EXCHCAS01
EXCHCAS02
EXCHMB01
The CAS servers are running both HUB and CAS roles. We have an external address exchmail.thedomain.com that uses DNS round robin for SMTP mail. (two external IP's)
I have configured smtpRelay receive connectors so an internal server can relay out as a mailbox in the org. When the email hits CAS01 it relays fine. When it hist CAS02 it fails. Both SMTP receive connectors are configured identically. Both receive connectors were built on the idividual CAS servers.
Any thougths on why this is happening and how to fix it?
