The easies way, is to edit /etc/aliases on box1 and have the line:

root: youremailaddress at box2.com

then run (as root)
$> newaliases

that way all the email (ie. logwatch report, tripwire, etc) sent to the root 
on box1 will automatically be forwarded to youremailaddress at box2.com.

And yes, AFAIK sendmail service has to run for that to work. By default 
sendmail does not listen to the external interface (only local loopback). If 
you're still not convinced that's secure enough, use tcpwrapper to refused 
all connection to sendmail in /etc/host.deny, and/or block port 25 using 
firewall.
