I keep getting these return message from our exchange server 2003. can some offer a suggestion what to check. We only have this problem for some outgoing domains.
I also get this error when I look in the Queue:
The connection was dropped due to a SMTP Protocol Event Sink
I verified we are not on a blacklist
we have our reverse DNS setup properly
Any other things I should check?
