My Exchange users can successfully send and recieve internal email... they can also send external email BUT when someone external tries to send them email, they immediately get a bounced back "Mail Administrator" email with:
or something similar from their ISP.
Each user receives email from two email accounts - username@testdomain1.com and username@testdomain2.com. STRANGE thing is that testdomain1.com email works perfectly fine... i waited a couple of weeks to make sure the first domain had no problems after switching everyone from an external POP account to Exchange - and now I've made the same mx record changes for the second domain to point to my exchange server but this time I'm having this relay problem!
