Safabyte SfbEmailVerifier is a versatile component for validating email-addresses. It allows you to add email address validation to both .NET WinForm and WebForm applications. Developers are able to detect invalid email through validation syntax, check bad or accepted email addressed with Black List and White List. By setting validation level to its maximum level, email address will go through 6 checking levels: address syntax, black and white lists, Mail Exchange records, Smtp Connection and Mail box. Furthermore, developers can verify email-addresses by using multiple-threads through the system thread pool.

Key Features

1. Verify email addresses up to five levels of validation, from syntax check to querying accounts on mail server.
2. Verify lists of email addresses with a single method call (SfbEmailVerifier can verify email addresses in DataTable, DataSet, IDataReader or IList).
3. Verify email addresses in a list file (email addresses are delimited by character ;, or space).
4. Support Multilingual: you can customize log messages in SfbEmailVerifier via LocalizationSettings property. 
5. Alow you to write verification log to a stream.
6. Retrieve mail exchange servers (MX Records) associated with an email address.
7. Auto detect DNS servers in your network.
8. High Performance internal MX cache: DNS queries are expensive and SfbEmailVerifier has an option allowing you to cache the MX Records that have been determined for further use.
9. Includes fully configurable classes for regulating DNS and SMTP connections.
10. Fully support both event-driven (asynchronous) and blocking (synchronous) application designs.
11. Allows user-interface events to process during synchronous use.
12. High-Performance Multithreaded verification: SfbEmailVerifier allow you to use multiple threads to verify email addresses with only one line of code.
13. No knowledge of SMTP or DNS protocols is required. Encapsulated classes provide theory of operation.
