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(_dot_)com -> http://xyz.muada.com/iljitsch

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