I was recently in your shoes myself.  I was using a seperate mahine to run 
my filtering on, and sendmail was my biggest hurdle!  I had it working on 
a test domain, then added the filtering.  That all worked, so I pointed my 
real domain's MX through that box and all hell broke loose!  Everything 
started bouncing.  I had missed somehting in configuring sendmail.

If you can swing it with the person maintaining your DNS, have them set up 
a testdom.gatech.edu pointing to a test box for you to test with.  Then 
you don't have to burn the mignight oil until you have a handle on what 
you need to do.

In my limited experience, I'd look at the sendmail config files.  There 
probably should not be any difference between the production version and 
the one for filtering except the milter information in sendmail.mc/cf.

I'd offer more words of wisdom, but my experience is with trying to get 
the filter box to relay to another mail server. 

Good luck!
