As mentioned you could try  milter-ahead or smfsav, run as a milter from 
sendmail to drop the connection prior to the DATA command in the SMTP 

One note, apparently the same self appointed police at backscatterer.org 
also blacklist you for attempting to cut down on spam by using sender 
callouts.  So if you use smfsav, disable SAV or you will just get 
blacklisted again.
