What options do I have to parse the e-mails that have bounced? I am receiving the bounce notification from e-mail servers but don't know what to do with it.
Thanks
Edit: I just want to know how to do it. If I receive 30k bounces per day, how can I remove the e-mails from my newsletter?
The short answer is that you have problems. Bounce messages have no standard format (except perhaps some).
If you control the list, I suggest setting a Errors-To header and/or the explicit Return-To header. If you can afford the cost of queuing each message individually, then using VERP 1 addressing is a huge win and should mostly solve your problem.
To fully understand the implications of setting these headers I suggest reading the details from a site like Wikipedia.
