You seem to be assuming that "non-obvious" ids are independent of each other
and that as a result it might be easy to mistype one id into another. What
about a scheme where it is *impossible* to get from one id to another without
making at least 3 mistypes? At least what would happen then is that you will
get the message returned with "no such user".
Of course, if your mail system allows you to *validate* local users before
you send the mail as well then most of the mis-sendings disappear too.
