If you haven't been receiving password reset notifications or alerts for threads you've subscribed to and you're a Gmail user, be certain to check your spam folder. If the messages were marked as spam, even accidentally, there's a strong chance Gmail may have blacklisted the Goon site (and this server's IP address).
The best fix in this case is to simply unflag the message as spam. If you don't want to receive such messages, it's better to set your profile preferences as appropriate or delete the messages (rather than marking them as spam).
