Email Address Validator

Description

Plugin will automatically check all the inputs with “email” type and suggest a correction to the visitor in case of a typo.
Example: “john.doe@gmal.com” instead of “john.doe@gmail.com”.

This is especially useful when sending transactional emails back to the customer after placing an order, submitting a contact form, etc.

Sending emails to the non-existent addresses will result in so called “bounces” which will decrease reputation of your sending IP address.
Your server’s IP address might get blacklisted and your customers will no longer receive emails from you.

Plugin is using “Mailcheck.js” library:

From the email checkers I've tested, this plugin does an alright job. Caught most of the invalid emails in our test list and identified all Catch-alls. Seems to have problems with emails from @yahoo.com domains though.
