 Local domains not allowed, e.g. user@localhost, user@localdomain, user@somehost.localdomain
 
 IP addresses not allowed, e.g. user@127.0.0.1, user@10.0.1.1, user@8.8.8.8, user@147.102.5.97, user@192.168.1.245
 
 Number of characters in top level domain must not less than 2 or more than 6,
 e.g. username@yahoo.c, username@yahoo.corporate

email - the email address to validate.

Throws:

javax.mail.internet.AddressException - thrown on validation error.
