We have an AS/400 on v4r5m0 and an MS Exchange Server on 5.5 I have been able to setup the AS/400 to send and receive mail. The problem that I have is receiving mail on the AS/400 under name@domainname.com I'm able to received under name@hostname.domainname.com How can I enable the as/400 to be able to received mail this way (name@domainname.com)? Any help would be greatly appreciated.
