I noticed there was a useful project by Derrick Ko of Kicksend at https://github.com/Kicksend/mailcheck, and thought it would be useful for GWT projects or for JSF projects to have java code to accomplish the same thing. It looks like through empirical testing the use of mailcheck has increased the quality of their data.

So all I've done is a simple port from Javascript to Java, leaving out the jquery integration. I've moved stuff around to fit the style of Java and my own style, and put in JUnit tests that should (at time of writing) cover the same scenarios as are tested for in the Kicksend version of mailcheck.

There's no reason why JSR 303 or Spring validation couldn't be added to this project to lessen the need for glue code, but I haven't put this in yet because an email address that has a suggestion isn't 'invalid' necessarily.

I haven't put this in any maven repositories, so your best bet is to grab the code and install the project in your maven repository.

You can then add it your project (assuming you use Maven) by referring to it using the maven coordinates:

<dependency>
    <groupId>com.intercognition</groupId>
    <artifactId>mailcheck-java</artifactId>
    <version>0.1</version>
</dependency>

I've created it so that it can be easily used programmatically or configured by an IOC container like Spring. You can get up and running quickly by doing the following:

MailCheck mailCheck = new MailCheck(new DefaultConfiguration());
EmailAddress address = mailCheck.suggest("user@hotmail.cod");

This will return you an EmailAddress object giving you a suggestion. If a suggestion could not be found, a null EmailAddress will be returned.
