Is Lucifer the same as the Anti-Christ in the Christian belief? ( They're 2 different entities in my faith ). Because Sam was thought of as the next Anti-Christ back in season 3 so I just wondered.

I haven't been getting any LJ-notifications for my flist's birthdays lately and apparently they've all gone to my junk folder, along with a few of the replies to LJ comments and posts. I got most of the latter in my usual inbox, but ALL of the former had gone to my bulk folder. Anyone else with this problem? Any idea what I should do about it?
