EmailVeracity

Description

The Email Veracity Plugin adds a validation function that you can use in models that have email attributes. It will validate email addresses three ways:

1. Checks that the email address is well-formed
2. Checks that the domain name in the email address has a DNS entry
3. Checks that the DNS entry for the domain has an MX record
