I think you should be able to do what you want by setting up procmail and 
the sanitizer AS IF the system were a gateway -- that's how it behaves, 
at least to some extent, if you have .forwards and aliases that point to a 
domain that's not yours.

I may be confused (read that as wrong) though.  If you want me to try to
"fix"  your setup, please tell me:

   what version of sendmail you are using
   what OS and version is running
   what version of perl you use
   the content of your -.mc file from which you built sendmail.cf along
     with any other m4 files you may have customized
   if you did not make sendmail.cf that way, send me sendmail.cf
   some examples of user .forwards and aliases for which no filtering

I realize you might not want to send some of this in the clear through 
email.  If that's the case, clean it somewhat first (replace your domain
name with something else, make generic failure examples, and so on) and
tell me where you cleaned it.

Don't expect a speedy answer -- I am slow, but I will get there:  I'll
troubleshoot it on a three-node local net.
