This is exactly what this Open Source PHP class does since many years ago, except that this class can handle grey listing responses. http://www.phpclasses.org/emailvalidation Basically it returns 3 possible responses: valid, invalid, and undetermined. Valid, means the SMTP server would accept the message (although it may reject it later). Invalid means the SMTP server would reject the message. Undetermined means that for message would not be accepted now, but could be accepted later, which is usually what servers that implement greylisting cause. -- Regards, Manuel Lemos Find and post PHP jobs http://www.phpclasses.org/jobs/ PHP Classes - Free ready to use OOP components written in PHP http://www.phpclasses.org/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
