I've successfully used the ICertificatePolicy hack before to connect
to https but this doesn't seem to work for sending Gmail. Please see
the following code:
using System;
using System.Net;
using System.Net.Mail;
namespace Tester
{
class Program
{
static void Main(string[] args)
{
var from = new MailAddress("from at gmail.com");
var to = new MailAddress("to at gmail.com", "Sr. To");
var mail = new MailMessage(from, to);
// Set the content.
mail.Subject = "Subject";
mail.Body = "Test";
// Send the message.
SmtpClient smtp = new SmtpClient("smtp.gmail.com");
smtp.EnableSsl = true;
smtp.Credentials = new NetworkCredential("from at gmail.com",
"p4ssw0rd");
// No worky???
ServicePointManager.CertificatePolicy = new
TrustAllCertificatePolicy();
smtp.Send(mail);
}
}
public class TrustAllCertificatePolicy : ICertificatePolicy
{
public TrustAllCertificatePolicy() { }
public bool CheckValidationResult(
ServicePoint sp, X509Certificate cert, WebRequest req, int problem)
{
return true;
}
}
}
I'm getting the typical certificate exception:
System.IO.IOException: The authentication or decryption has failed.
---> System.InvalidOperationException: SSL authentication error:
RemoteCertificateChainErrors
at System.Net.Mail.SmtpClient.<SmtpClient>c__38 (System.Object
sender, System.Security.Cryptography.X509Certificates.X509Certificate
certificate, System.Security.Cryptography.X509Certificates.X509Chain
chain, SslPolicyErrors sslPolicyErrors) [0x00000]
Is there any way to do this w/o the need of importing the certificate chain?
Thanks.
