Ultimate Email Validator is a 100%-managed .NET class library that adds powerful and comprehensive e-mail address validation to your .NET applications without sending e-mails to recipients. You can easily validate bulk e-mail addresses loaded from many sources such as list, text file, CVS, DataTable, and DataSet using single or multiple threads with a single line of code.

Ultimate Email Validator's Key Features
Verifies email addresses up to five levels of validation, from syntax check to querying accounts on mail server.
Verifies lists of email addresses with a single method call (UltimateEmailValidator can verify email addresses in DataTable, DataSet, IDataReader or IList).
Verifies email addresses in a list file (email addresses are delimited by character ;, or space).
Supports Multilingual: you can customize log messages in UltimateEmailValidator via LocalizationSettings property.
Alows you to write validation log to a stream.
Retrieves mail exchange servers (MX Records) associated with an email address.
High Performance internal MX cache: DNS queries are expensive and UltimateEmailValidator has an option allowing you to cache the MX Records that have been determined for further use.
Auto detects DNS servers in your network.
Includes fully configurable classes for regulating DNS and SMTP connections.
Fully supports both event-driven (asynchronous) and blocking (synchronous) application designs.
User-interface events to process during synchronous use.
High-Performance Multithreaded validation: UltimateEmailValidator allows you to use multiple threads to verify email addresses with only one line of code.
No knowledge of SMTP or DNS protocols is required. Encapsulated classes provide theory of operation.
Validate email addresses up to 6 levels
Support for .NET Full Framework, Xamarin iOS, Mac, Android, Mono, .NET CF, and .NET Core, Standard (will be available soon)

Intuitive and Fully Documented API
Connect and validate emails with a few lines of code using the intuitive API of ComponentPro's Ultimate Email Validator. By using 100% managed code written in C#, the component takes advantage of the numerous built-in features of the .NET Framework to enhance performance, moreover, the library is CLS compliant, and it does not use any unsafe blocks for minimal permission requirements.

Our classes are fully documented with detailed example code which helps you shorten the learning curve. If your development environment is Visual Studio, enjoy the full integratation of the online documentation. Just mark or select a keyword and press F1 in your Visual Studio IDE, the online documentation is represented instantly.

Comprehensive Email Address Validation
The Email Validator component makes it easy to validate bulk email addresses within your .NET application. In addition, it allows you to retrieve the MX Records of a specified domain with only one line of code.

By default Ultimate Email Validator checks your system for your primary DNS server. As a benefit, you can specify custom DNS Servers in the DnsServers property of the EmailValidator class. Ultimate 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 Email Validator session.

Task-based and Event-based Asynchronous Patterns
Our products support the latest Microsoft .NET Task-based Asynchronous Pattern introduced in .NET 4.5 Visual Studio 2012. Now you can simply write your asynchronous methods using the async and await (C#) or Async and Await (VB.NET) keywords. For some reason if you would like to use Event-based Asynchronous Pattern we support it too.

Supports HTTP Connect, SOCKS4, SOCKS4A & SOCKS5 Proxy Servers
Ultimate Email Validator provides full support for Proxy Servers such as HTTP CONNECT, SOCKS4, SOCKS4A, and SOCKS5. By simply setting a few properties, you are able to validate bulk e-mail addresses through the desired proxy server, providing your application with the greatest flexibility and highest level of security available.
