I need to be able to process bounced emails from mailing lists
for my clients. How can I setup a email pipe to automatically forward bounced emails to a php script for processing.
The script would grab the bounced email address, compare it to the mailing list, count many times it has been bounced, and remove address from list if bounced x number of times.
I know "Announcement List" feature does this, but my clients require more control over the subscription/unscription process and the list itself.
