I get daily emails from a specific source. I've added the address that these emails come from to my Address Book. I've ensured the whitelist is set up to prevent these from going to my Junk folder. I've continually marked them as Not Junk. The e-mails show up in my inbox, but when I view them, it displays the message for 5 seconds tops, then transfers it to my Junk folder. I have to then go to my junk folder, mark it as Not Junk (which I've been doing every day for a week now), which then moves it back to my Inbox where I can view it.

I don't understand why these messages keep getting moved to my Junk folder, though. In Address Book and I've marked them as Not Junk. Frankly, this has become really stupid and annoying.
