Mine stopped as well. They were making it to my gmail account until really today, but then got stock without being forwarded (not marked as spam). My filters are set to forward emails from fiestastform.com...like this:
Matches: from
support@fiestastforum.com)
Do this: Never send it to Spam, Categorize as Forums
That should do it, right? All the other email I get was being forwarded fine. Really just meant that I was forced to poke my gmail account. Not a big deal, just an extra step (or go direct to the forum URL, which defeats notification).
Now, notifications are not landing at my gmail account at all.
