Email Validator

What is Email Validator ?

Email Validator finds invalid email addresses without actually sending an email, in your mailing list or in your website form! ASP.Net email validator will make sure you keep valid email addresses of your customers and stay connected! ASP.Net email validator is highly scalable email validator solution. Capable of handling large volumes of addresses and  it can be easily integrated into your website to check addresses on-the-fly!

Features

WinForms and ASP.Net support

Email Validator allows you to validate email addresses and MX Records, from any .NET application. Email Validator can be used from ASP.NET web pages, to windows forms, to web services. The only limitation to using Email Validator is your programming imagination.

Invalid email detection syntax validation

Email Validation Control first checks syntax of email address before actually checking with SMTP server and mailbox.

DNS lookup on the domain for validity

By default ASP.Net Email Validator  checks your system for your primary DNS server.  As a benefit, you can specify specific DNS Servers in the form of a comma-delimited string. ASP.Net Email Validator  will attempt to connect to each one, until a successful connection is made, and then use the first responsive DNS Server for the remainder of the ASP.Net Email Validator  session.

High Performance Internal MX Cache

Email Validator has a built-in high performance internal cache that stores previously looked-up MX Records.  For example, once the MX Records for hotmail.com have been determined, Email Validator no longer makes the expensive DNS Queries again, to determine those records. Instead, when the 2nd email address is encountered, that belongs to hotmail.com, Email Validator checks it's internal cache to see if the records are there, and then uses those records.   By default the Email Validator cache is set to time out every 15minutes, however, this time can be set by the programmer, to  be minutes, hours, or even days!

Bad Email Address Internal List

How many times have you seen the email address 'test@test.com' or 'a@a.com' or 'asdf@asdf.com' entered into your address list?  While all of these addresses are technically valid, they are probably not too useful to you or your list. Email Validator provides the capability to add these addresses to a 'Bad Address' list, and every time they are encountered, Email Validator automatically fails them.
