Remember, most e-mail gets bounced because (not your's personaly Chain, but in general) your e-mail server is or may be on a "Black list" due to a high amount of spam or attacks or such. It happens a lot these days. The best practice is to have a few e-mail address from different locations (Gmail, hotmail) etc. Chances are if you are getting bounced, its because your ISP is on the "Blacklist" or black hole list.
Besides my "amigalounge" email, I use hotmail, and I also have a Gmail account (which I never use) and a "Shaw" account (my ISP). The best way to get a hold of me is through hotmail, it is the e-mail I always check and use.

Also, Craig only checks his e-mail every few days, and don't be surprised if he doesn't reply right away. He is just swamped these days.
