Nope. Only way is upgrade to E2003 and use recipient filtering or a 3rd party product of some sort. You could always add those bogus addresses to a DL with no members and they would simply vaporize with no NDR.
-----Original Message----- From: Dickenson, Steven [mailto:[EMAIL PROTECTED] Sent: Wednesday, February 04, 2004 6:46 AM To: Exchange Discussions Subject: Check recipients at SMTP time With MyDoom and spam bouncing around forging invalid e-mail addresses, I'm generating tons of bounce notifications that don't go anywhere. I noticed that Exchange 5.5 doesn't verify the recipient during SMTP time, but after the message is received. Thus the bounce messages. This sucks. Is there anyway to configure Exchange 5.5 IMS to reject messages at SMTP time with 5xx error when an invalid recipient is given? Note, I'm only talking about recipient names with the correct domain. My Exchange server does correctly give a 550 for relaying attempts.
