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 !
