Hi,

I would like to validate an email address from .net. Now before you scream
regular expression I would like something a bit better than this.

I would like to validate the domain, and maybe lookup to see if the domain
has a valid MX record.

can anybody tell me if this is possible using .net and if so point me in the
right direction.

If it is possible then would it also be possible to make sure that I get an
authorative answer and not just an answer from any old server.

many thanks in advance.

You can do some pretty decent DNS stuff with the System.Net.Dns object, but
there are also some more powerful third-party components that would probably
save a lot of hand-coding, such as the one at:
http://www.asp.net/ControlGallery/Co...740&tabindex=2

You should be able to find a ton more over at the www.asp.net control
gallery just by searching on DNS.

Hope this helps,
