sendmail on Gauntlet

["Bowden, Kevin" <bowden_kw () nns com>]

I'm trying to forward mail through an isolated firewall (Gauntlet 4.1a /
Solaris 2.5.1 - all patches) to another firewall (same config) that is
attached to the internet.  The Isolated firewall wants to send mail direct
and cannot find the destination host.  How do I tell the isolated firewall
to forward mail to the Internet attached firewall?  I have tried
'DFhostname.com' in sendmail.cf to no avail.  That was the best I could come
up with, not being familiar with sendmail.

a.b.com ---- FirewallA ----- b.com ----- FirewallB --------- Internet

> From the simple diagram above, I have mail flowing from the Internet to both
domains, between domains, out from b.com, but not out from a.b.com.
FirewallA does DNS from the b.com domain and can resolve addresses.  I just
need to have it forward its mail to FirewallB for it to deliver to the
internet.

Thanks!!
