I am at a location that uses an Intel Inbusiness email station and outlook express for it's email. If I try to send an email to a roadrunner address, the email will not get sent. It will go around in the system for 24 hours and then be returned as undeliverable. The weird thing is, if I send one email to a roadrunner address and have it circling around the system, I can send a second email to that address and it goes through ok? Obviously roadrunner is no help and they feel it is something in our system and intel no longer supports this system. Anyone have any ideas?
