Sorry to resurrect a very old thread but this appears to not be working for me over the last week. From recent posts on another thread, this appears to not be limited to PMs but is also affecting a bunch of other things.

I have verified that the messages are not in my spam folder, either locally or on my email server... if they're getting sent out at all, they're not arriving at my server.

Can someone look into this? Notification of PMs is extremely important. Thanks.
