EmailVerify.NET is a powerful Microsoft .NET software component that verifies e-mail addresses with various tools, including:
 
• Advanced syntax verification, according to IETF standards (RFC 2821 and RFC 2822, among others)
• DNS validations, including MX record(s) lookup
• Disposable e-mail address (DEA) validation
• SMTP connection and availability checking
• Mailbox existence checking, with greylisting and temporary unavailability support
• Catch-all testing
 
It is written completely in managed code (C#) and is compliant with Common Language Specification (CLS), so it can be used with any other .NET language, including VB.NET, C++/CLI, J#, IronPython, IronRuby, and F#.
 

 
EASY TO USE
-------------
 
Designed from the ground up to make the developer's life easier, EmailVerify.NET's whole architecture lets you perform a full e-mail validation with just a single method call, whether the job is as simple as a syntax check or as complex as a mailbox existence test.
 
Here's what it takes to validate an e-mail address (C# sample):
 

var verifier = new EmailVerifier();
var result = verifier.Verify("john@example.com", VerificationLevel.Mailbox);
 
if (result.IsSuccess)
{
Console.WriteLine("The mailbox exists!");
}
 

Could it be any simpler? Of course not. ; )
 

 
POWERFUL AND COMPLETELY CONFIGURABLE
-------------------------------------------
 
With a very stable and mature code base, EmailVerify.NET supports six different e-mail address verification depths and allows you to configure every possible aspect of the validation process, including adherence to IETF standards preferences, network-related settings, and timeouts for multi-threaded activities.
 
In the following snippet, for example, EmailVerify.NET is configured not to allow domain literals in e-mail addresses, while allowing comments and quoted strings. Furthermore, the component is set to use a particular DNS server (instead of a system-configured server) for its lookups:
 

verifier.AllowDomainLiterals = false;
verifier.AllowComments = true;
verifier.AllowQuotedStrings = true;
 
// The component will use just the provided DNS server for its lookups
 
verifier.DnsServers.Clear();
verifier.DnsServers.Add(IPAddress.Parse("10.0.1.18"));
 

On top of that, the component exposes various events that notify the user about any change in the e-mail address validation's progress, including verifications starts/ends and depths advancements. This way, whether your project is a desktop-based application, Web-based, or a class library, you may use these notifications to react accordingly at every phase of the verification activity, as well as to present a message to the end user or to insert a row into a database.
 
For example, this is the way to bind to one of the provided events and write a message to the console every time there is progress in the validation process:
 

verifier.VerificationTaskProgressChanged += (sender, args) =>
{
Console.WriteLine("The address {0} reached level {1}",
args.Task.EmailAddress,
args.CurrentLevel);
};
