Yes, and No! If you use the ReturnPath header SOME/most email servers will bounce msgs that they can't deliver to an actual mailbox back to you (others drop such msgs onto an Admin somewhere, lose them in the ether (the msgs not the Admins...) etc, etc). Accordingly, use a distinct address for this/email filing rules. Opt-in email schemes which send a welcome/confirm email to new customers do so for this reason - the only way to verify an email address is to use it (and get some feedback from the addressee). Of course, once you have 'located' a new user, you still have to cope with those who close email accounts without advising you... It's a wonderful world! =dn -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
