If it helps anyone, all my email responses from Gerald go to my Spam folder. Not sure why, but I'm in the corner with every email that I have sent him has gotten a pretty quick response (within a day I'd say). Anyway, just throwing it out there in case responses are hitting your Spam folders. I don't often check for stuff there unless I'm not getting responses I think I should be.
You should be able to fix that so it hits your inbox and doesn't get redirected to the SPAM folder. Every email client I have seen has the option to allow you to mark the sender address as "safe" or "not SPAM". It should be honored even if the email content trips SPAM filter weights. Try right clicking on one of the messages in your SPAM folder and see what options your client gives you.
