PM and post reply email notifications
 

For some reason my two vBulletin forums are no longer sending out PM and post reply email notifications.

I was running both sites on VB 3.8.3 when the problem started (I think mid December) and have upgraded to VB 3.8.4 since hoping this would resolve the problem. It hasn't :(

Nothing in the Admin CP has been changed that would cause this to happen (that I can tell).

Is there a way to check if VB is actually generating and sending out these emails?

PS My host is GoDaddy and I have asked them if anything has been changed on my server and they say not.

Thanks in advance.
