The ISP optonline (
http://www.optonline.net ) is blocking mail coming from our server, and not being very responsive to inquiries. If you are one of the many spamgourmet users who have a forwarding address with them, this explains why you're not getting email through spamgourmet. They may fix the problem, but as I mentioned, haven't responded much so far. If this affects you, you can a) contact optonline and see what's going on, b) change your forwarding address to be somewhere else, or c) live with it, I guess.
