I've used the west-wind wwipstuff to send email, and it seems to to what I want.

My problem is that I need to send out about 400,000 emails, and I'd like to have some way of keeping track of the ones that don't go though so I can remove them from our mailing list. This means I have to have some way to recieve email (the bounce-backs) and then delete that record from the table. Anyone done anything like this or have any suggestions?

Thanks!
