Hi,

You can use the following code:

MailMessage message = new MailMessage();
                message.To.Add("[email protected]");
                message.From = new MailAddress("[email protected]");
                message.Subject = "Test";
                message.SubjectEncoding = System.Text.Encoding.UTF8;
                message.Body = "Test";
                message.BodyEncoding = System.Text.Encoding.UTF8;
                message.IsBodyHtml = true;
                message.Priority = MailPriority.High;

                using (var client = new SmtpClient())
                {
                    client.Credentials = new System.Net.NetworkCredential("username", "password");
                    client.Port = 465;
                    client.Host = "host";
                    client.EnableSsl = true; 

                    client.Send(message);
                }

smtpClient.EnableSsl = (smtpClient.Port == 465);

what i understood is that you want to enable the ssl for the smtpclient if the port is 465. above is the code for that.

explain more if this is not your requirement.

Hi, please take a look at this:

.NET built-in mail class doesn't support the needed SSL method (implicit SSL) and there's nothing to do with this: the reason is explained here.

There exist third-party SMTP client components that do both explicit and implicit SSL and have other cool functions. For example, Rebex.Mail or our SecureBlackbox.

Please mark the post as an answer that helps/solves your problem.

This code does not work for me when trying to send SSL emails via a well-known commercial hosting company's secure mail server on port 465; they require username/password. I can send non-SSL mail fine, but authenticated SSL mail always times out. Do you know for certain that this code works?

It doesn't work because System.Net.Mail doesn't support Implicit SSL.

This does not work. You should test your own suggestions.
