Email address verification for your C#, VB.NET, and ASP.NET applications

The Email Checker .NET component offers .NET developers sophisticated email verification
from within their applications. Validate email address syntax and verify against the domain’s mail server.

The Email Checker provides full syntax checking of email addresses as well as
domain verification and user name testing using SMTP. Select the level of
checking you require from a fast syntax check, to a DNS server MX record lookup
to ensure the domain name is valid and a mail server is configured, to finally
an SMTP check of the user name against the mail server.

Part of the award winning .NET Internet Component Suite,
the component is designed specifically for .NET and is written in 100% managed C# code.
