Good post, and I enjoyed reading it. Just had a bit if information for you though:

You're correct that this normally isn't used when writing something yourself, but the email writer simply wanted to prove a point. He wrote:

It's more of a religious "respect" thing. I'm sure you've heard of Christians capitalizing "God", even in the middle of a sentence, out of respect. Well, this is sort of the reverse. The writer is informing you that he is not messing up his capitalization. That is, the second "satan" (after the period) should normally be capitalized for beginning a sentence, however the writer is not capitalizing it in order to not give "satan" any respect in the same way "God" should be given respect.
...or something like that.
A silly thing if you ask me, but that's what they're doing.
I also think that capitalizing God in the middle of sentences is silly. God doesn't require our respect in pedantic, ornery ways, if He even exists. Such things belittle more than they give respect, in my opinion. But I'll do it as much as I can remember anyway because I do have respect for the many, many people who beleive such a thing is incredibly important. And because it is those people who are, generally, my main target-audience in places such as these.
I won't be, however, not-capitalizing "satan" at the beginning of sentences... such things are too far even for me
