The example demonstrates how to send message via Gmail, which requires TLS. http://www.phpclasses.org/smtpclass Anyway, I recommend that you use that class in conjunction with this other for composing and sending RFC compliant MIME message. It helps avoid problems that make message get trapped in spam filters: http://www.phpclasses.org/mimemessage -- Regards, Manuel Lemos Metastorage - Data object relational mapping layer generator http://www.metastorage.net/ 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
