Maybe if it were a standard all developers used, with MUA support. We 
have a whitelist keyword (either in the subject or an X-Fnord: mail 
header) on the ghostscript.com mailing lists, and it's been a disaster. 
We don't have to clean the spam filters anymore, but only the core 
developers can remember how to post to the lists, so it effectively 
killed outside traffic. I don't recommend it.
