I switched up the mailing system for the forums. Currently, a lot of mail was being sent to the junk/spam folder of mailboxes. I managed to fix this problem by editing the code behind the website. It should go to the main folder, and it should no longer be marked as spam. I'm working on fixing this with different parts of the website but, this should work by default with registration and contact. I haven't checked this out for registration but, I need to test this feature before making it live.
