If I ever try to send you a message, your server will inappropriately 
block my server and give me no means to get through to postmaster at 
your domain.

My Exim4 server is configured to retry every minute for the first 15 
minutes, specifically to get messages delivered through greylisting 
systems as quickly as possible.

This isn't me playing the devil's advocate; this is how my server was 
already actually configured.
