For the moment, I am just going to verify that what is entered is a valid
email format. Verifying that the email exists, may come later.
Thanks for making me think about this, though.
Note that it's only possible to verify that the email-address is correctly structured and a syntactically correct. There is no way to verify that an email-address actually exists, ie. that a recipient will receive emails sent to it.
