Registration and forgot password email not working on this forum?

Sorry if this is off-topic for this forum, but the forum software itself seems to have a problem. I could not get it to send me a password reminder, and when I registered as a new user I didn't get the email.

(So how did I log in? Searched back through my mail to find my original password)

Have you checked to make sure things didn't just get redirected as spam?

Emails generally seem to be working, as I'm still getting "follow-up post" notifications.
