Right, but is the only solid way of doing it.  The provider already have
the infrastructure to maintain the mail account and thus the costs of
adding a new data field a marginal.

Of course one could setup a service to do this for example by appending to the mail address before the lookup.  However this
introduces a lot of costs (user help desk), annoyance (the user need to
register with that service), and centralization.

Iff enough people are interested in confidential mail communication
competition will force all providers to add this.



Die Gedanken sind frei.  Ausnahmen regelt ein Bundesgesetz.
