PHP mail() not working

I use the php mail() function for my contact pages, forgot password and registration verification.

The mail() function is not working. Is there a reason? Perhaps the server is delaying sending?

UPDATE:

It seems to be working, eventually. But the delay in the email being sent is very problematic when somebody is trying to reset their password.

Suggestions?

Buy when the share price is low. Sell when it is high!

Aside from scjessey’s stellar advice (he forgot to mention which stocks), check the FULL headers in a received message and sort through the time stamps of the message to see where the holdup is.
