Postfix: handling undelivered/bouced emails with a script

[manarak]

I'm running ISPConfig3 on my server, and I'm looking into the possibility of automatically processing undelivered emails with a script, if possible PHP.

So I've been looking through the /var/vmail/ directories and the incoming mail is easy enough to detect, allright.

So I would like to run a PHP cron that looks through the mailbox and does "something".
Ideally, I would like to remove the bounced messages from the mailbox.

But I could not find any description of the mail server's (is it postfix?) behavior, and if removing a message was as simple as just deleting it from the /new directory?

Is there a description of postfix somewhere?

If you use Maildir structure you can simply delete a file and the mail is gone.

grep -HRe '(MAILER-DAEMON|550)' /var/vmail

should get you started with emails that couldn't be delivered.
