Mail Queue Problem: Messages Get Stuck?

[webcanada]

Hi guys,

I've had this problem before, and it seems to come up periodically, and I don't know what I can do to fix it/troubleshoot it when it happens.

Randomly (?) messages will start to accumulate in the queue. I just checked recently and there were about 3,000 messages. About 2,900 of those were "failure notices".

NEW messages added to the queue (for example, when a PHP script generates an e-mail) would just sit there.

I deleted all of the failure notices from the queue, and had about 150 messages. They still would sit there. I tried restarting SMTP/Qmail, rebooting the machine, nothing.

Then, randomly, the messages start to go out.

I looked in the log, but I can't really tell what is causing it to get stuck (if its noted there).

Any help and suggestions are appreciated.

Thanks,
Peter.

It is hard to say exactly what can be the problem but you can try to check following category in SWsoft's FAQ which is related to Mail service: http://faq.swsoft.com/category22.php

for example, this one http://faq.swsoft.com/article_22_169_en.html

Hope you could find useful information there.
