Sure, that isn't meant to be used in a WHERE condition on a 100k row

incomming data is validated.
and doesn't tell you whether the user part of the address is valid (and in
general, there's no way to
determine that short of actually sending a message). So what's the

The point is to validate as good as possible, and as you said yourself,
the user part can't be validated further.
