MTAs don't care about To: (unless they've been messed with). qmail
cares about the envelope sender.
"Someone B. Else [[EMAIL PROTECTED]]" is not a valid envelope sender
at the SMTP level. qmail looks up the host part "otherdomain.com]" and
fails. You could argue it should check the syntax, but that would be
code added only to change the wording of an error message.

I think the user put in something strange and the MUA did its usual
thing without checking the result. This would happen with several
non-MS MUAs as well.
