Unable to send mail using smtp c#
Below is my code:
{
mm.Subject = "test";
mm.Body = "test";
mm.IsBodyHtml = true;
SmtpClient smtp = new SmtpClient();
smtp.Host = "smtp.zoho.com";
smtp.EnableSsl = true;
smtp.Port = 465;
NetworkCredential NetworkCred = new NetworkCredential("support@xyz.com", "XXX");
smtp.UseDefaultCredentials = true;
smtp.Credentials = NetworkCred;
smtp.Send(mm);
}
I am getting following error:
