I'm trying to send a SMTP message to a non-windows mail hub via CDO. The\nmail hub is doing a reverse DNS lookup to verify my identity (no big\nsurprise) but the name it is trying to verify is not the NetBIOS name of the\nsending machine. For example, the NetBIOS name of the sending server is like\nxx-yyyy-zzzz and the mail hub is trying to verify the name xxyyyyzzzz. I\nhave tried getting support from the mail administrators with no success. I\nhave searched our DNS system for entries matching the dash-stripped machine\nname with no success.\n\nMy questions are\n\n1. Is Windows or CDO stripping the dashes (-) from the server name anywhere\nin the message transmission (in HELO or EHLO)?\n2. What should I be looking for in the DNS system?\n3. Should I be looking at other name resolution systems?\n\nAny assistance would be helpful.\nThanks,\nBruce.
