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:
