RE: Accessing DNS MX Records

[Joel Fritz <JFritz@xxxxxxxxxxxxxxxx>]

This probably isn't really to the point, but domain validation is a
relatively small piece of the puzzle.  I think the gethostbyname API might
do this for you.  InfoCenter has some good documentation.  There may also be
a way to use nslookup in batch.  It might be easier to see what bounces.

I never got as far as looking for MX records when I was trying to do
something in the same vein, because a large number of the e-mails I had to
work with were typed in by customers in a free form text field.  A lot of
the questionable e-mails had perfectly OK domain names like "aol.com".
After stripping out embedded spaces and improbable characters like '<' you
may have a nice looking e-mail address that just doesn't belong to anyone.

OTOH, it would be cool to have something that does this.
