How to ignore a invalid certificate?

[tobecwb]

I have a server with a self-signed certificate (my email client consider this a invalid certificate, and FluentEmail too).

How can I send a email ignoring the invalid certificate? tried the following code:

var email = Email
  .From("[email protected]", "Me")
  .To(message.Destination)
  .Subject(message.Subject)
  .Body(message.Body);

email.Sender = new SmtpSender(new SmtpClient("smtp.server.com", 587)
{
  Credentials = new NetworkCredential("username", "password"),
  EnableSsl = false
});

await email.SendAsync();

I always receive the error The remote certificate is invalid according to the validation procedure

.netcore 2.0 has the ServicePointManager class. Looks like you'd set the ServerCertificateValidationCallback on it

ServicePointManager.ServerCertificateValidationCallback = 
    (sender, certificate, chain, sslPolicyErrors) => true;

Also, if you want to disable SSL, on the current version you have to set the UseSsl flag on the SmtpSender class. It overrides the SmtpClient setting.
