For root, you can't get away with just eliminating "root" as an
EXPOSED_USER in sendmail.mc and relying on MASQUERADE_DOMAIN because
that will result in translating root at localhost.localdomain" to
"root at some.real.host", which would be very wrong.

You can use genericstable to translate root at localhost.localdomain
to some other real address.  You'll want to uncomment the
"FEATURE(`genericstable')" line in your sendmail.mc and include a
line like the following in /etc/mail/genericstable:

   root at localhost.localdomain   somebody at some.real.domain.tld

You'll also need to uncomment the "FEATURE(`masquerade_envelope')"
line in sendmail.mc and be sure "localhost.localdomain" is being
included in class {G} by including a line:
      "GENERICS_DOMAIN(localhost.localdomain)dnl"
(You can also use a GENERICS_DOMAIN_FILE to do that.)

I'm tempted to say, "Now rebuild sendmail.cf, restart sendmail, and
Bob's your uncle," but (a) I'm not your uncle, and (b) I might
have left something out.  So, I won't.
