Geez, it's nothing that fancy, folks. operator@wherever seems to have
simply done
/usr/lib/sendmail gnu-win32@cygnus.com
with an empty body fed into stdin. Sendmail will stick in an
Apparently-To: synthesized from the recipients on the command line if
there's no "To:" line in the message (which there obviously isn't: he
seems to have fed an empty file to sendmail). The other headers are all
synthesized by sendmail in its normal course of operation..
The "To: " header is not guaranteed to exist..
