Strangest thing is occuring on our exchange server. Internally we can send
and receive Email and even send attachments. We can receive Email from anywhere
even attachments. When we attempt to send out email it goes through as well.
The problem is that when we add an attachment to an email and send it outside
of the building it just builds up in the IMS connector que. Does anyone have
any suggestions or answers for me?

We also recently switched ISPs. Do you think the problem may be with them?
And if so, What could it be?
