E-mail Validation for .net
PatNorSoft Email Validation is a true native 100% managed class that can be implemented for both Webforms and Winforms. It checks email in two steps: 1- Check if the email has a valid syntax. 2- If it is valid then proceed with a special DNS look-up to check the validity of the email address. Although email validation can't be 100% foolproof, WebStorm Email Validation Component can cut off bad email addresses up to 80% in you database.
