Sendmail forwarding

[robert@mail.provision.net]

Hello all
Any quick pointers in setting up sendmail to forward all incoming email to
an internal mail server? We need all incoming traffic to stop at the
firewall where it passes web/email traffic to a new box which is replacing
the existing webserver. This new box needs to then forward all email to
the existing mail server which will be behind the firewall with no direct
incoming access from the internet, only the LAN.





    LAN -----> Internal Mail Server -----> Firewall <----> Internet
                                              |
                       ^                      |
                       |                      |
                       |                      V
                       \<-- <-- <-- <--  New WebServer


I know there is a simple way to tell sendmail on the webserver to do this
but I wasn't able to find any info on this at sendmail.org this morning.
I'll keep looking but if someone could tell/point me in the right
direction it would be appreciated!

Thanx
