As others have pointed out, you _can_ do this, there is nothing to 
prevent it.

If your real question is, "Will most mail software automatically 
recognize that mail to <random> should use this key?" The 
answer is almost certainly, "Not by default." Most popular mail tools 
can be configured to do so, but if you're looking for a solution that 
will work "out of the box" this almost certainly isn't it.

hope this helps,
