Send an e-mail using it? If the right person gets the e-mail, then
it's valid?

You'll have to define "valid". Valid syntactically according to
<what>? Will be accepted by an SMTP server somewhere? Corresponds to
a real person?

Make sure it has an '@' in it. Possibly require at least one '.'
after the '@'.

Trying to do anything more than that is just wasting your time and
annoying the mule.

To be is to program.
