This is MS-Windows; there's no sendmail here.

But that's the MTA, which should not matter in this case, I think.
The mail-user-agent is set to sendmail-send-it here, which is what
should matter.  The important question is why Date is not generated in
the mail buffer in your case.

Yes, but that shouldn't matter.
