Email Validator 1.0.0
Email Validator - Email Validator checks deliverability of email addresses. It does so by first performing a DNS query
on the domain name of each email address in order to determine the address of the mail server
servicing that domain. Once the mail server is found, a connection is made in the same way as your
ISP's mail server would make a connection. Email validator will first attempt to use the SMTP VRFY
command to determine deliverability. If the VRFY command is enabled, the mail server will report
whether the email address being tested is in fact deliverable, Email Validator will then close the
connection and report the result.
In many cases the VRFY command is disabled on SMTP
servers. If this is the case for any given mail server, Email Validator will then attempt to
simulate the delivery of an email message. During this process, the mail server will report whether
or not it can accept a message for the email address being tested. Once this is reported, Email
Validator will close the connection and report the result. NO EMAIL IS ACTUALLY SENT. Email
Validator never gets to that point, so the owner of the email address will not receive any message
as a result.
Once a list of email addresses has been tested, the user may export all
addresses along with test results or simply export all deliverable or non-deliverable addresses in
order to clean an existing list or build a new one containing only deliverable addresses. The
result for anyone who runs a mailing list, i.e. ezine and newsletter publishers, businesses,
political parties, non-profit organizations, etc. can save time and money by sending mail only to
deliverable addresses and not have to clean delivery failure notices out of their inboxes.
