note 22580 added to function.mail

I tried to send a lot of emails using php 4.2.1 on IIS5 on a 2000 server and when the SMTP queue get to close to 1000 messages in the queue, the server reboot and do a save dump on a gub check. Any insight reasons? Also I am trying to change the SMTP port so PHP mail would use another SMTP on port 26 or example but I can't. The documentation here state that there will be a config added in PHP 4.3 but where can I get php 4.3 ?!? -- http://www.php.net/manual/en/function.mail.php http://master.php.net/manage/user-notes.php?action=edit+22580 http://master.php.net/manage/user-notes.php?action=delete+22580 http://master.php.net/manage/user-notes.php?action=reject+22580
