I have a php script that sends out e-mails for a newsletter. It uses sendmail, which goes to qmail on this box. I sent out about 10,000, and about 2,000 went out fine, but I still show almost 8,000 in the qmail queue.

Could someone tell me how I could figure out why these emails are still in the queue and not going out, but the others went out fine?

Thanks.

Please let me know if you've found a solution ... We are sitting with a similar problem - the php mail function does not work as expected ...
