Hi Guys,

This one is a real bad one!
My mail server crash and was forced to build a new one and import pst's.
When we try and send mail to two domains in particular we get an "Undeliverable" error msg back. We could send to these domains before and they are up and accessable from other sites. Our mail server works fine with all other sites. The msg that comes back says:-

"Unable to deliver the message due to a communications failure
The MTS-ID of the original message is: c=GB;a= ;p=metaphorix;l=CONQUEROR-030307121032Z-55"

I think there is some thing that I missed in the configuration. Can someone help out on this one?

Thanks.
