Thanks for the reply. I'll ask the ISP about throtteling next time I talk with them. I would also like to mention that I am also getting intermitent results when just sending a single email. One if the web pages I am testing is a support request form. When the form is submitted it sends an email to me so I can test that it is working. But sometimes it never makes it. In this case I wouldn't thing that throttleing would be the cause. Sometimes when I start working on it at 8 in the morning and do a test run it never makes it. In that case nothing has been sent through PHP for at least 8 hours. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
