This example was running couple days before and now it gives me an error:

const client = new SmtpClient();

const params = <ConnectConfigWithAuthentication>{

await client.connectTLS(params);

await client.send({

  subject: "Mail Title",
  content: "Mail Content，maybe HTML",
});

await client.close();
