That is what I think.

Could be. The cache settings were not set that high but you never
know with exchange. This is what I expect the problem is.
In fact, I was going to try and say some more here but I just deleted
it because it occurred to me that the old mail server may be saying
to the exchange server that it cannot relay on since it would have
updated its own dns. They did not turn off the old service yet but
since the MX record no longer points to them they are trying to send
it on to us...

They seem to be the local exchange servers that returned the error to
the users who were trying to send email. (They forwarded the errors
on to help us diagnose the problem). I can receive mail in my domain
from them and my exim runs both domains in the same config.
