Because you like reinventing the wheel and doing the same work twice?
    
By memory, in an thread about the same topic just a few days ago, Fredrik
Lundh posted a link to Perl's FAQs that suggests a method for "validating"
email addresses: treat it like a password and ask the user to type it
twice. That will protect against simple typos and input errors.

For everything else, send to it and see what happens.
