You can setup a standard qmail installation on one host. This would
listen on port 25 and accept emails.
On that host use
   /var/qmail/control/smtproutes
to send the emails on to the host behind the firewall, by adding a line
    domain:desthost:port
See "man qmail-remote" for more information.
On that host you can configure (e.g. via tcpserver) to have qmail-smtpd
accepting mails on that port.
