E-mail notification not working?

[amb]

I have e-mail notification turned on for some topics but I don't get any such emails when new replies are posted.  Is this feature broken?  Yes, I checked my spam box and they're not there.

Never mind, I figured it out.  It works now.
I had forgotten that I set the email address here to go through google mail as a redirector, and google was marking the notifications as spam and dumping them into its spam box.
