That is one more reason to not use SMTP connections for queueing many messages. If you use sendmail or equivalent and the MTA is properly configured, there will be no SMTP disconnect and reconnects to deal with. Using SMTP is simply a bad idea unless your MTA is in a separate machine. Personally I use qmail. It never establishes SMTP connections when you are queueing messages. When I want to deliver messages to many recipients I call the qmail-inject program directly, instead of Qmail sendmail wrapper that is used by the mail function by default. Actually I use the MIME message package that comes with drivers specialize in qmail, sendmail, SMTP and mail. Each driver carries its bag of tricks to optimize deliveries among other options to speedup bulk-mailing in general. http://www.phpclasses.org/mimemessage -- 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
