One of the easiest ways to do this (assuming by "email address" you mean an address suitable for SMTP - i.e. RF822) is to use the package InternetAddress in the JavaMail extension - which throws an AddressException if the String does not match RFC822 syntax.

Also, if you're using Struts, you can use their built-in validator which has FieldChecks.validateEmail() -- granted you never call this directly, you set it up through the Struts Validator (it's also credit card, date, url and a variety of primitives and ranges).

Do you want to check the syntax, whether the email is in use, or whether the email was really send by the person, owning that adress?
