I configured my email settings to connect to sendgrid on port 587 and use tsl:

Code:
$config["useragent"] = "CodeIgniter";

$config["protocol"] = "smtp"; // or mail or sendmail

$config["mailpath"] = "/usr/sbin/sendmail";

$config["smtp_host"] = "smtp.sendgrid.net";

$config["smtp_user"] = "apikey";

$config["smtp_pass"] = "<SENDGRID-API-KEY-HERE>";

$config["smtp_port"] = 587;

$config["smtp_crypto"] = "tsl";

$config["dsn"] = FALSE;

// ETC

I wrote a short script on a controller:

Code:

    public function mailtest()

    {

        

        $this->load->library('email');

        

        $this->email->from('[email protected]', $this->config->item("site_name"));

        $this->email->to('[email protected]');

        

        $this->email->subject('Email Test ' . microtime(TRUE));

        $this->email->message('Testing email config with new port');

        

        $this->email->send(FALSE);

        header("content-type: text");

        echo ($this->email->print_debugger());

        die("done");

    }

When I look at the output of print_debugger(), I don't see any STARTTLS command:

Code:

Is the server output truncated or something? How can I be sure that my server's interactions with the SMTP gateway are encrypted?
