SMTP with TSL

Hi everyone,

I've been trying to use cURL with a tsl connection to an smtp server.  I've found the following problems:

1.  PHP curl with telnet and tsl can't connect.  Anyone know how to do this?
2.  There seems to be no SMTP support with the php libraries.  However I saw this example for libcurl: 
http://curl.haxx.se/libcurl/c/smtp-tls.html.  Does this mean it might be coming?

Hacked Solution:
Using curl with an https connection I was able to find a hack that allowed me to send out simple SMTP messages
by putting the entire smtp command strings and message into the customrequest field setting when
connecting to the server.  Example snipit:

        curl_setopt($this->curl_handle, CURLOPT_URL, "https://$this->host:$this->port";);
        curl_setopt($this->curl_handle, CURLOPT_SSL_VERIFYPEER, true);
        curl_setopt($this->curl_handle, CURLOPT_SSL_VERIFYHOST, true);
        curl_setopt($this->curl_handle, CURLOPT_CAINFO, "cacert.pem"); // local root CA copy
        curl_setopt($this->curl_handle, CURLOPT_CAPATH, "./");
        curl_setopt($this->curl_handle, CURLOPT_RETURNTRANSFER, TRUE);
        curl_setopt($this->curl_handle, CURLOPT_HTTPHEADER, "");

        $out = "AUTH LOGIN\r\n";
        $out .= base64_encode($this->user) . "\r\n";
        $out .= base64_encode($this->password) . "\r\n";
        $out .= "MAIL FROM: <$from>\r\n";
        $out .= "RCPT TO: <$to>\r\n";
        $out .= "DATA\r\n";
        $out .= "To: $to\r\n";
        $out .="From: $from\r\n";
        $out .="Subject:  $subject\r\n\r\n";
