Hi all
Could someone double check this for me please:

strEmail =3D txtEmail.Text
strPattern =3D "^[\w-+\.]+\@([\w-]+\.)+\w+$"

It should accept an email address of

Click here to reveal e-mail address

But when I try a DNS check using System.Net - it fails.
Other emails are successful though so I know the DNS checker is working.

Is my regex right - because our mail server has problems sending to this
specific domain (and other demon domains, but that's another issue..)

Damian, you probably should send more code to [aspngfreeforall] if the
regexp is not the problem.

Yeah=20

I've just tried the tools over at Hexillion thx to (Dave Wanta) and I'm
fairly sure that it's an ongoing problem with them, not us. I was just
making sure on the reg-exp as I'm no expert on it.

Cheers

There are some very good tried-and-true regexes on http://regexlib.com. Also,
Michael Amundsen has an MX record checker at
http://webservices.eraserver.net/mxchecker/

which you might try as a sanity check.
