Spam Blocker automatically Removes Attached Viruses, and can block unwanted email by Country, Email Address, Domain, and Keywords using our pre-defined Blacklists (or create your own). You can setup Spam Blocker to check multiple email accounts. You can even Import your address book from Outlook, Outlook Express, Eudora, or any .txt file so you don't have to worry about email from people you trust getting marked as spam. It's so simple, you'll wonder how you ever lived without it !

Having problems with the email addresses in your mailing list?Are you tired of getting bounce backs every time you perform a mailing? Email Validator will solve your email validation problems. Email Validator is an assembly that requires the Microsoft .NET framework to run. It is used to validate email addresses at different levels. Email Validator does not have a GUI front end, it is a server component that can only be accessed programmatically. Email Validator can be used on signup forms or it can validate huge lists of email addresses from one address to million. Email Validator validates email addresses at four different levels. Syntax, Domain, SMTP, and Mailbox levels. To validate an email address, simply create the EmailValidator object, pass it the email address and the level of validation to check, and Email Validator will do the rest. For some code examples on how to use Email Validator, click here. Email Validator does not actually send an email, but it can check the remote mail server to see if the server will accept an email for that address. The only way to truly check to see if an email address is valid, is to send an email. Here's a more detailed explanation of the 4 levels of validation provided by Email Validator.

EmailValidator

ASP.Net Email Address Validator Control finds invalid email addresses without actually sending an email, in your mailing list or in your website form! ASP.Net Email Address Validator Control is highly scalable email validator solution. Capable of handling large volumes of addresses and it can be easily integrated into your website to check addresses on-the-fly ! Email Validator Control allows you to validate email addresses and MX Records, from any .NET application. Email Validator Control can be used from ASP.NET web pages, to windows forms, to web services. The only limitation to using Email Validator Control is your programming imagination. Email Validation Control first checks syntax of email address before actually checking with SMTP server and mailbox. By default ASP.Net Email Address Validator Control checks your system for your primary DNS server. As a benefit, you can specify specific DNS Servers in the form of a comma-delimited string. ASP.Net Email Address Validator Control 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 ASP.Net Email Address Validator Control session. Email Validator Control has a built-in high performance internal cache that stores previously looked-up MX Records. For example, once the MX Records for hotmail.com have been determined, Email Validator Control no longer makes the expensive DNS Queries again, to determine those records. Instead, when the 2nd email address is encountered, that belongs to hotmail.com, Email Validator Control checks it's internal cache to see if the records are there, and then uses those records. By default the Email Validator Control cache is set to time out every 15minutes, however, this time can be set by the programmer, to be minutes, hours, or even days! Email Validator Control provides the capability to add addresses to a 'Bad Address' list !
