My Email is Annoying

I have a terrible suspicion that I'm not receiving all of my emails. It's really strange because I'll have long gaps of no emails then all of a sudden I'll receive 20 at a time. I've had notes from online groups that I've joined stating that I need to reactivate my account because they've received returned emails and for this reason, my group accounts were deactivated.

Very, very annoying.

Until later. . .
