double at – email triangulation

Why has no one come up with an email routing/sending system that can use multiple at (@) signs?

For example, why not have an author@antipaucity.com@apple.com?

The email could be routed to both auther@antipaucity, and @apple – and/or could force-route mail through the first mail system (presuming credentials were available).

Let the flames spark.

  1. It’s been done. Replace the first @ with % and the mail system is supposed to route it to the mail server after the at, strip off everything after the @, replace the % with @ and send it on its way. It pretty much died because spam caused mail servers to stop forwarding.
