That is even worse. Keep in mind that the SMTP server of sendmail or equivalent MTA, ends up calling the sendmail program for each individual message that it receives. It is the same operation, except that you are communication directly with the sendmail program with pipes when you use mail(), and when you use SMTP it uses SMTP connection that triggers sendmail program calls to actually queue the message instead of attempting to to deliver it. The bottom line, if you use qmail, postfix, or sendmail configured to queue the messages (instead of attempting to deliver them) you will always be much faster queueing messages. Just watch out your server disk space and CPU when you are attempting to deliver too many messages. -- Regards, Manuel Lemos PHP professionals looking for PHP jobs http://www.phpclasses.org/professionals/ 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
