Failed internet email

My company sends out newsletters every week to it subcribers. We receive alot of failures. I am looking for a way to export the failures into a files to be imported into sql. My problem is that the failures message comes back as a message with the original message as an attachment. I am looking for the best way to do this. The only way I can see is create a event script that removes the attachment and copies it to another folder. Then a second script that exports it to a comma del file. any sugestions would help.
