Apparently-To: is a joke header that was in the original Berkeley
sendmail.  If you run /bin/mail and give it recipients as arguments,
and the message text on standard input -- the way pre-Internet unix
programs, like uucp, like to do -- /bin/mail just dumps the message to
sendmail, and sendmail, seeing that there is no To: line, inserts an
Apparently-To: line.  One of the first things I did to sendmail at Sun
was to fix this to just insert a To: line.  Berkeley didn't buy back
the change in 4.2 (I guess they like jokes) and I don't know if their
4.3 sendmail still has it or not.

Anyway, don't blame the Bitnet gateway, it's just Yet Another Sendmail-Ism.
