As an aside, any NOS worth its salt shouldn't be compromised at all by
somebody knowing an account name. For example, I'll bet you an espresso
that there is an account on that box whose username is "root".

I think that this is because DNS doesn't like it. Or more properly,
because DNS name queries are case-insensitive, so sendmail always
lowercases everything to avoid confusion.
I could be wildly wrong on my details here.

Yup.

Nope. You'll hit the same issue.

Won't make any difference. This is Correct Behavior(tm).
I suppose there might be some way (say, Courier backed by an SQL
database and hacked up not to follow some RFC or another) to make this
work, but you're bucking long tradition if you try. You're also asking
for trouble when someone used to the common behavior tries to send mail
to "james" on your now-case-sensitive MTA.
