EmailValidator

ASP.Net E-mail Address Validator Control finds invalid e-mail addresses without actually sending an e-mail, in your mailing list or in your website form. ASP.Net E-mail Address Validator Control is highly scalable e-mail validator solution. Capable of handling large volumes of addresses and it can be easily integrated into your website to check addresses on-the-fly. Supports .net 4.0 and VS 2010 E-mail Validator Control allows you to validate e-mail addresses and MX Records, from any .NET application. E-mail Validator Control can be used from ASP.NET web pages, to windows forms, to web services. The only limitation to using E-mail Validator Control is your programming imagination. E-mail Validation Control first checks syntax of e-mail address before actually checking with SMTP server and mailbox. By default ASP.Net E-mail Address Validator Control 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 E-mail Address Validator Control 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 E-mail Address Validator Control session. E-mail Validator Control 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, E-mail Validator Control no longer makes the expensive DNS Queries again, to determine those records. Instead, when the 2nd e-mail address is encountered, that belongs to hotmail.com, E-mail Validator Control checks its internal cache to see if the records are there, and then uses those records. By default the E-mail Validator Control cache is set to time out every 15minutes, however, this time can be set by the programmer, to be minutes, hours, or even days. E-mail Validator Control provides the capability to add addresses to a Bad Address list.
