It's "sendmail".

Or even:

Very interesting.
Unused in practice, I believe.
I hope nobody plans to say "sendmail does this, so it must be right".
Please don't use an implementation that was done before the RFCs
to justify wierd/bogus behavior. It causes big problems for authors
of other MTAs (as they might be "forced" to implement that wierd
behavior too). sendmail allows all kind of bogus things (mostly
to deal with broken software) which are not valid according to the
RFCs. The RFCs should (clearly) define what a protocol should look
like, not some implementation.
