smtp2web solves the problem of getting the messages. As far as I can tell, there are 3 ways to get access to the messages: 1) Control your mail server, use something like procmon to forward mail to a script 2) Rely on smtp2web or some other mail server to forward mail to a script 3) Poll for messages via SMTP or IMAP I chose #3 with IMAP over Gmail (configured for my domain). The real problem I am having is identifying and categorizing non-delivery responses / bounce mails.
