As a slight aside on this discussion, I had read somewhere --- citation lost --- that the munging of mboxes to escape lines beginning "From " in a message to ">From " messed up PGP signing. Is this valid? [I suspect not, because I see lots of signed messages and you can't *all* be using maildirs, can you? :-)]
