Thanks for the reply.

I do not want to query the actual email server because it can be used maliciously. Picture a botnet sending 15,000 emails a day to the mail server causing my clients IP to be blacklisted as a spammer. Then picture it happening to many servers until the IP address appears on almost every blacklist.

I used to have a verification routine that contacted the email server, although not sending email, but decided it was open for abuse so I am writing a verification routine that only uses DNS servers to verify the domain name. It is not as robust a solution but much safer.

I am honest with the client about what I can do safely, and the limitations of doing it this way.

I eliminate the roger@las.vegas but not the mickey.mouse@disney.com
