Oh, sorry.

Easily done by specifying the server to relay to in
/etc/mail/mailertable

To relay mail for mydomain.com and its subdomains to the host at
10.1.2.3 you'd have

mydomain.com	[10.1.2.3]
.mydomain.com	[10.1.2.3]

You need the usual stuff in /etc/mail/access to accept mail for those
domains too.

Cheers,

Phil

This is what it says
Set your MailScanner box(es) to be MX(s) for the domain (i.e. available
to the outside world), running MailScanner.
A Windows box running Exchange on an IP address not available to the
outside world (in our case 192.168.10.5)
On the MailScanner box, there is a file called /etc/mail/mailertable. It
put the following line in it:
ourdomain.co.uk smtp:[192.168.10.5]
(The brackets tell sendmail to bypass DNS resolution.) 

Add the domain name to /etc/mail/relay-domains
This tells sendmail to push the mail off to the Exchange server, but
crucially, it does this AFTER MailScanner has done its work.
