I'm having a huge headache with email over the past week and i'm ready to take a lump hammer to the server!
We have a dedicated server with WHM installed and currently using the default exim configuration, and everything works fantastic, until it comes to sending mail to an email hosted through Microsoft Exchange!
All emails in and out of the server are showing as accepted and delivered without error, there are no bounce backs so i'm at a complete loss as to what the issue is, i am however almost certain it is a server issue.
We have tested half a dozen domain emails hosted on the server and sent to two completely different clients who we know both use Exchange. Both clients have had their IT support companies look into possible causes and so far nobody has been able to explain why out emails are not getting through.
If anyone can make any suggestions or possible solutions they will be very much appreciated.
Many thanks in advance
