I'm not sure why, but servers have the IP pool of our server in it as a "SPAM" source. Unfotunately, there's not much I can do as many emails are bouncing from the server itself not making it to the users inbox (which is a usability issue in my eyes).
Anyway, if you DO NOT receive any emails from this forum, or you're missing your confirmation email, please email me (my address is now public) and I'll manually authorize you. If you can, ask your Email provider to remove the following IPs from their ban list (as RCForum will use one of these): 72.233.32.114 to 72.233.32.118 it would be appreciated.
