Not to my knowledge, and I just tested it on my system and it's not, and my
config should be standard for this. A quick grep of the docs doesn't show me
any documentation at all on case sensitivity, so it looks like they removed
it completely at some point -- I know at one point there was an option to
turn it on; that seems gone.

Not unreasonable, but compare it to the old definition. It used to be case
sensitive, even though we all ignored it. Now, it may be case sensitive. The
intent is clearly to make it non-mandatory. That means you can't depend on
it being allowed unless you control the e-mail completely. And that means
while I shouldn't arbitrarily do weird things to it simply because I can,
you can no longer assume I WON'T do weird things to it, because the standard
no longer tells me not to...
