Enables .NET applications to verify bulks of e-mail addresses for correct syntax or existence. Validation levels include RegEx check, DNS MX lookup query, SMTP connection and test send attempt without actual sending a message. , can take data from string array, DataTable or MS SQL database. Multi-pass, tolerates greylisting.
Written in 100% managed C# code. Can be used in desktop, console, and ASP.NET applications developed in C#, VB.NET and other .NET languages. Supports .NET 2.0/3.0/3.5/4.0/4.5/4.6 (including Client Profile), both 32-bit and 64-bit. Also supports Xamarin (Mono on Linux, iOS, Android).
Features: - 'async/await' methods for building scalable and responsive applications - Massively multi-threaded for better performance (can process hundreds of thousands of addresses). - SMTP PIPELINING and DNS caching for even better performance. - Can process single addresses, string array of addresses, DataTable or IDataReader (such as to process data from MS SQL Server). - Dynamic whitelist and blacklist (via events). - Extensive samples which show not only basic scenarios but also advanced cases which cover greylisting and multi-pass check to tolerate temporary errors. - asynchronous methods; - events and error handling features, memory/file logging, debug functions, etc; - documentation available as .CHM file and online; - royalty-free distribution.
