How does it fail? Have you configured your Internet Mail Service to allow relaying? This is dangerous if this particular IMS is exposed to the Internet, however. If the non-Outlook clients support authentication, you should require it to send mail. See these links for more information:

Am running Exchange 5.5 SP3 which receiving incoming e-mail from our VMS system. Well, our VMS system has run into many issues over the past weeks and e-mail has been directly affected by this. In an effort to take the VMS system out of the equation and keep mail running properly the powers that be want to make the Exchange 5.5 system our incoming mail point and have it route messages not address to it to other systems on campus. My problem is that I cannot get this darn thing working like it should. Currently our domain is central.cua.edu In attempts to test the routing, I set up a secondary box to receive mail in the same domain, in this case test1.central.cua.edu Attempts to send to this box, for instance, [EMAIL PROTECTED] are successful if the message originates from Outlook C/W, but messages from any other mail client using the SMTP on the Exchange system fails. I have created an MX record for the test domain as well as an A Record in the DNS. What am I doing wrong? Essentially we want mail sent to @central.cua.edu to obviously get delivered locally to the Exchange system and anything else i.e. test1.central.cua.edu or test2.central.cua.edu to go to the respective systems. I have looked at the Address Spacing on the IMS and Routing and even attempted some changes, but none have come to fruition. Ideas ?
