Hi there,
I am facing a problem when I try to validate an email address entered by the user. Syntax validation is ok but when I try to check whether domain exists or not it is giving an exception that unable to connect to the domain specified. I will show u the code:
string[] host = (txtEmailAddress1.Text.Split('@'));
string hostname = host[1];
IPHostEntry IPhst = Dns.Resolve(hostname);
IPEndPoint endPt = new IPEndPoint Go to the complete details ...
