Stop SPAM by protecting all email addresses from email harvesters in just a few clicks! Junk email (a.k.a. spam) is a part of everyone's life if they ever put their email address on the web. For HTML authors, site admins, and for people who want a little credit on the page that they put online, it is a constant problem. You want to include your email address on the page, but you don't want your email address to be harvested by spambots. If you own a site on the web, you're practically guaranteed to get spammed, right? This conventional wisdom has held true for a long time; with the proliferation of automatic "spambot" programs that suck the email addresses out of every site they visit, it is usually only a matter of days between the launch of your site and your first spam. There is an effective solution to the problem. It's easy to implement and - most importantly - it works! The best thing you can do is encode your email address so that browsers can see it and spambots can not. This is what this tool does. How it works: our tool will replace all your e-mail addresses on your page with specially encoded email addresses. The AEVITA Stop SPAM Email introduces codes that spambots will "choke" on, but which a normal mailing program ignores. Therefore people can still send you email but spammers can't get your address! The coded email address will work on just about any browser out there. The user does not need to have Java or JavaScript enabled for it to work. But this is not all - the AEVITA Stop SPAM Email can even attack spammers by generating large lists of fake email addresses. Spammers have to validate addresses they have, so if they will have a lot of false email addresses in their lists, their life will get strongly complicated. Stop SPAM Email - an uncannily effective weapon for any webmaster battling against spam!

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.

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 !
