You see, Exchange does not close an SMTP session when an incoming address is incorrect. It takes the message into the queue and then checks against the directory whether the address belongs to a valid user. If the address is not valid, then it generates an NDR.
-----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Thursday, January 29, 2004 9:11 AM To: Exchange Discussions Subject: IMS indicates outgoing from <> appears to be Spam Forgive me if this is elementary but my question is that if I have tested and have had others test and verify that my mail servers do not allow relaying why do I constantly see messages in the IMS Outbound Queue that show mail is from "<>" to various domains? All of these messages appear to be Spam. I seriously doubt I have infected machines doing this. Exchange 5.5 SP4 on 2k SP3. Any thoughts or direction is appreciated. Thank you.
