I programmed this for a client using a PowerShell script based on the DSNs they received. I don't own the code, so I can't post it, but I can share that the Lumisoft NET library is a godsend for doing this kind-of stuff. It doesn't make it "easy", because you've got to program around a few bugs in their MIME implementation, but it makes it quite feasible and not extraordinarily difficult.
And if you use the POP-3 interface or the IMAP interface, the Exchange version doesn't matter (and you can use various 3rd party mail servers as well). Regards, Michael B. Smith MCSE/Exchange MVP http://TheEssentialExchange.com From: Campbell, Rob [mailto:[EMAIL PROTECTED] Sent: Tuesday, March 11, 2008 7:39 PM To: MS-Exchange Admin Issues Subject: How to programmitically capture delivery failures. Problem: An application has a user database with email addresses. The application will send an email to the users in the database periodically. The application developers want the emails addresses from any of these that came back undeliverable captured and sent back to them to clean up the database. Environment - Exchange 2007 Edge and Hub Transport servers. Exchange 2003 servers on the back end with the mailboxes. (No 2007 mailbox servers yet). We're using an outsourced mail host (Message Labs) for delivery, so the protocol logs aren't much help. All outbound email will initially be accepted by the servers at Message Labs, so there won't be any delivery failures reported in the protocol logs on the Edge servers. Any email returned to the sending address should be a DSN. There shouldn't be any replies or other inbound email to that address. If I can get the incoming DSN's routed to a text file, I can parse out the information I need. Originally I was thinking about just letting them go to BADMAIL, but it seems that Exchange 2007 doesn't give you that option.
