They are logged in a "connection log" in exchange 2007 and above.
I don't think that exchange 2003 logged the connection filtering results (but I'm prepared to be wrong). Regards, Michael B.

I agree and was thinking the same thing. What happens, however, if the connection is dropped b/c of sender's listing in an RBL? Would there be anything in the SMTP logs in that case? All my RBLs are configured on edge devices so I don't have a way to know what would happen if they were configured directly on Exchange.

If you don't have anything in this server logs then that means that messages don't reach to your server and problem is elsewhere. And it's useless to search something from spam folders and other places when message haven't even reached to your server. If that is the case then you must start pester your customers ISP's or IT staff(if they have any) for more information about problem. Markko -----Original Message----- From: Silvio L.

Hello, Could someone suggest where can I look for the reasons for some disappearing messages ? Customers that were able to send email to our people are saying they sent the emails, but our people say they never received. This started some time ago. Nothing in logs, nothing in spam filters. I will disable all filtering to see if it impacts , but don´t think so. Have perused through the 1k messages / day of spam, but the "phantom" messages are not here. Now , I know that users cannot be trusted not to delete a Mailer Daemon message without reading, but this is happening with people who used to communicate via email normally since a long time ago. Any suggestion for searching the problem ? System is 2003 - R2 with Exchange 2003. Thanks, Silvio.
