Some UNIX systems disallow upper case characters in the username
(Sun OS 4 man page says so...)

It's an option in sendmail (as nearly everything) (F=u for the mailer
makes the name case-sensitive). If you use procmail for delivery, it
will usually force the name to lowercase. So your best bet is
not to use upper case characters (some older termcap entries even assumed
that the terminal has only upper case characters when you login and type
an upper case character first!).
Proposal: make this a compile- (or even run-) time option.
