.NET Email Validation Library Specifications


"I was looking for a .NET component that would save me the time and trouble of reading RFC 821 and writing a bunch of complex regexes. Instead, I found the Kellerman .NET Email Validation Library which goes far beyond simple validation and detects so many things that I didn’t even think about: fake emails, disposable addresses, grey listing and much more. Plus, like the other Kellerman libraries, it is very easy to use with just a line or two of code. Highly recommended."

Wayne Hiner

Simple to Use Validate an email, or a list of hundreds of thousands of emails, with a single line of code.
Fake Email Pattern Matcher Did you know abc@abc.com is a valid email address? It has a valid syntax, a valid mail server and the mail server actually returns true for a mailbox check. The fake email pattern matcher recognizes thousands of bogus email addresses just like this example.
Disposable Email Addresses Prevent bots from posting messages on your message board by preventing them from using disposable email addresses. It recognizes thousands of disposable email domains such as mailinator.com, spamavert.com, and spamex.com.
Free Email Addresses One way to prevent fraud is to disallow free email addresses when customers order products on your eCommerce site. The .NET Email Validation Library recognizes thousands of free email domains such as hotmail.com, gmail.com, and rediffmail.com.
Detects Greylisting When grey listing is in place, a mail box check cannot be performed. The .NET Email Validation Library detects grey listing to verify the address at a later time.
Detects Blocking Detect when your mail server or IP Address is being blocked by anti-spam software. This happens in shared hosting environments when a spammer uses the same mail server as your business. It detects blocking by spamhaus, SPF, SORBS, SpamCop, spamblock.outblaze, 86.blacklist.zap, SORBS and many others.
