That would be a nmh-style Message-ID; the first number is the process
id of whatever generated that (probably post(8)), the second is a Unix
timestamp.  Do you have -msgid set in your profile for send(1)?

I think pretty much anything takes a -version flag?

From the code, that's calling LocalName(1).

What that does is: getaddrinfo(gethostname(), AI_CANONNAME).  So maybe
your resolver library canonicalizes your hostname to "localhost"?  If
getaddrinfo() fails then it falls back to the value of gethostname().
