Validate email addresses easily. .NET EmailValidation Wizard allows you to validate email addresses on multiple levels. Three levels of processing can be used to check the email address depending on the degree of validation you want. Quick syntax checking ensures the email address is in good form and also detects a lot of trick entries. Domain check ensures the email address is for a valid domain and Full Validation makes sure that the syntax is correct, the domain is valid and that there are valid MX servers with active SMTP services running.

.NET Email Validation Wizard is a class library for .NET that allows for checking of the syntax of an email address, domain name verification, and even MX record and server verification.

Using the basic syntax check is the fastest method to verify an email address since it runs through an algorithmic routine on the local processor without any network transfer delays.

With domain validation, a better validation is performed because it validates the domain for the address with DNS records using the local DNS server setting on the machine. The class communicates directly with the DNS servers bypassing the built in DNS functions for more control and speed. EmailCheck builds a list of invalid domains as different addresses are parsed for a faster look-up. If the domain of a previously checked and failed address is in a future address, no DNS lookup is performed thereby saving time.

With full validation, the MX records are pulled for the domain and the SMTP service is checked to see if it is running. If there are no MX records and/or the SMTP service is not running on any of the IP's associated with the domain then the check considers the address invalid. This is the most lengthy and should only be performed when the most comprehensive check is needed.

With the advent of Verisign changing the root DNS servers, Email Validation Wizard has checks against a couple of known IP's associated with the Verisign fall-back address and considers any domain that equates to them to be invalid.

The product is great for database cleanup, form entry validation, and a variety of other uses.
