I got the Zelda email in my inbox (Gmail). Emails from TechKeys are flagged by Gmail as "important" when they arrive for me. I think the trouble may lie in the remailer service you are using. Gmail popped up a phishing warning when I first opened the email, saying that it may not have come from your email address. Your remailer probably got flagged by Gmail recently, so people are getting them sent to the spam filter.
