We keep getting delay notices and then failures when our users are sending to one domain in particular.
I looked up the DNS info on the domain and got the following:
blahblah.net. MX IN 86400 mx01.blahblah.net. [Preference = 0]
blahblah.net. MX IN 86400 mx02.blahblah.net. [Preference = 0]
Preference = 0 means that it has the highest priority.
What happens when you have two that are set to the highest priority? Could this be causing the delay/failure notices.
We are running exchange 2003 sp2. Is there anything I could do on my end get it to go though?
