mail queue hangs

mmoorree4444

New Pleskian
Hello,
I am hoping somebody can help me here. I have an opt-in mailing list and have written a php application that will send the emails using mail(). When I test this it will send the 5 test emails through okay. My problem is when I send the list of 500 thru they all hangup in the mail queue.

I can get some of them to send if I go into service management are restart smtp(Qmail). In doing this it is only sending a portion of these. Then I have to repeat the restart process, until eventually they all send.

Is there a limit or can somebody tell me what is going on and what to check on.

Regards
Mike Moore
