In emails that I send, if you look at the Received: header chain,
you'd find a line that resembles,

            by smtp.gmail.com [...]

Received: lines are generally added by each MTA that the message
passes through.  In this case it was smtp.gmail.com that added that;
it's not under your control.  You can probably modify the "Hikaru"
part, as I believe that just comes from the HELO command your mail
client uses.  I'm not sure which part of the nmh configuration
that comes from, but it can't be too hard to find.

It derives from the (hidden/undocumented) client switch to send(1).
I'll try sending this message with "send -client HiddenHostname".
