    Most frequently rejected invalid addresses? (Ex03)

    I'd like to reject as much invalid mail as possible at the perimeter. For existing employees, external spam filtering works well, but for former employees, the mail passes through to the server. Rather than set up dozens of phantom addresses for blocking, I'd like to query Exchange and get a list of all invalid addresses tried during the past, say, 14 days. Then I can choose the most frequently used and block those.

    Trying to figure out where this data might be in Exchange 2003 is baffling. There are various helpful pages on the web for how to do diagnostics on non-delivery receipts, but I'm not sure that is the correct place to look. Anyone have any ideas?

    How about setting up one mailbox and deliver the mail for all former employees to that box. Once in one mail box you have a many options.

    That's what I do. I have a "FormerEmployee" public folder with the SMTP addresses of all the former employees, and all their mail goes into that folder. The folder has a "lifetime" setting of only a few days, so the mail just disapears.

    If a good mail gets accidentaly sent their, I have a few days to get it, or it's on a backup tape.

    Well....we do actually want to reject this mail promptly so that any legitimate sender realizes the box is closed. I just can't believe this information isn't stored somewhere. I miss my simple POP/SMTP server. <img src=/S/sad.gif border=0 alt=sad width=15 height=15>

    Is there something available from AD?

    Maybe but I'm very ignorant about AD. I'll ask my network guy.
