How about this:

As time goes on, an email address gets on more and more spam lists. One 
way to avoid this is to use an email address for some time, and then 
discard it. However, this has the unpleasant side effect that people 
who only know the old address can no longer send email. What could help 
here is a standardized mechanism that allows someone to take an old 
email address and from that discover a pointer to where the new address 
can be found.

This could be done in (at least) two ways:

1. A standard transformation:
   iljitsch at muada.com -> http://xyz.muada.com/iljitsch

2. An SMTP response code:
   522 DOES NOT ACCEPT MAIL SEE <url>
