First, I don't think messages coming from an internal machine should
firt go to the firewall and then to the internal email server and then
back to the firewall. All internal machines should send their mail
directly to the internal mail server, which should deliver mails
addressed to accounts on the local domain directly, and forward mails
addressed to the outside world to the firewall.

It's pretty standard that people like to have subdomains stripped, so I
think Gauntlet's sendmail's default is to take them out. However, in
the Gauntlet I've worked on (version 3.1 for IRIX running on IRIX 6.2)
there are specific entry fields in the admin GUI form to type in
subdomains that you don't want to have stripped off - it's on the
'Sendmail Configuration' GUI admin page. You just graphically add all
the subdomains you want recognized.

killers, ready to administer the coup de grace to merchants who had
sponsored decades of Little League teams and high-school yearbooks in
order to shave some pennies off a tube of Colgate.
