Found this on the web.

Code:

---

            Try
                Dim BB As System.Text.RegularExpressions.Match = System.Text.RegularExpressions.Regex.Match(Me.tbEMailTo.Text, "[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+(?:[A-Z]{2}|com|org|net|edu|gov|mil|biz|info|mobi|name|aero|asia|jobs|museum)")
                If Not BB.Success Then
                    MessageBox.Show("Please enter a valid EMail address.")
                    Exit Sub
                End If
            Catch ex As Exception

            End Try

You can check for proper fomratting easy enough but that still does not mean it is a valid email address.

For example I could enter [email protected]

As far as I know the only way to insure a valid email is entered is to send a confirmation to the email address and get a reply.
