ArGoSoft Email Validation service is based on the technology, which has been used in the Pro version of our Mail Server for years.

Validation occurs in real time.  The service resolves MX records for domain of destination mail server, contacts exchangers, and directly asks the server whether it would accept mail to the address.

This is the most reliable email validation technology, it has proved so for our users.

You can use our service on your ASP.NET pages - validate email addresses at "real time", when user attempts to submit a form, containing return address, or, when user enters an entry in a guestbook... You can use the service to reduce spam... Possibilities are endless...
