Re: [PHP] tracking Mials Which were bounced.
Seems like the general way is to create a mailbox (POP3 or IMAP) to accept the bounces, then check it periodically and mark the emails as invalid in your local database. I would set threshholds so you don't mark something failed that only bounced once - it could have been a mail setup error or something else; I'd say wait for 3 failures in a 7 day period at least. If you get 3 bounces by that point, the address is probably safely dead. You can use PHP's IMAP functions to check the mailbox (even for POP3) or a million classes or your own functions directly on the socket (POP3 is a simple protocol) - it also helps if you parse the bounced email message to process the return address and the mail code; perhaps build something better than just 3 failures = invalid, but actually determine if they're full out failures, or if they're just temporary bounces, etc. Another method: you could just parse mail logs, if you have access to them.

You send them with a bounce-address that uniquely identifies the recipient - when the email bounces, you know exactly which recipient it was. I typically have my mailserver do a quick database update to set a status for such bounces. /Per Jessen, Zürich -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

The hard part is the last sentence - there are so many ways to say mailbox full - half don't include smtp error codes, the rest tell you the same thing in thousands of different ways. -- Postgresql php tutorials http://www.designmagick.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
