Ah.  And after digging around a bit, I found this on my own machine:

$ cat /etc/nmh/mts.conf
# nmh mail transport interface customization file.
...
# Name shown in HELO header:
clientname: sss1.sss.pgh.pa.us

which you can match up against the first Received: line in my own
outgoing mails.  So that's probably a better place to configure
it than messing directly with send(1) switches.
