Looking for a little help, we have an exchange 2007 server here and the box runs all roles. I am trying to modify the bounce back of messages within, but don't seem to be able to find them.
We have a distribution list that when it sends email seems to get a few a month that start getting email delivery failures and it states the following
This is a delivery failure notification message indicating that an email you addressed to email address :
could not be delivered. The problem appears to be :
-- Recipient email address is possibly incorrect
Additional information follows :
-- Domain has no MX records or is invalid
This condition occurred after 30 attempt(s) to deliver over a period of 92 hour(s).
Then we continue receive these messages every four hours or so.
What can I change to stop it?
