Here is how it works at my place which uses a central mail server 
(Xmail) and RT is on a seperate host. I have an account (helpdesk) 
configured on Xmail which simple redirects all mail send to it to 
sendmail running on the RT host. There I have sendmail configured per RT 
  Wiki to accept mail on the helpdesk account and pipe it into 
rt-mailgate which gets it into the database.
Checking if your configuration of sendmail on the RT box works can be 
done by telnetting to port 25 and starting the SMTP protocol and see if 
it makes it into RT.
There is a possibility that you need to configure sendmail to accept 
email on its external interface (eth0) too. It already does this on by default. It depends on distribution how this is configured 
by default.

Hope this helps you,
