Experiments have proven that Yahoo's SMTP is very easy to use, but the so-called Sina one is actually not easy to use. I was stuck for a long time.

Method 4, given to the program written by socket Encapsulation class for sending emails using socket:

class sendmail{
var $lastmessage; //Record the last response message returned
var $lastact; //Last action in string form
var $welcome; //Used in HELO Later, users are welcome
var $debug; //Whether to display debugging information
var $smtp; //smtp server
var $port; //smtp port number
var $fp; //socket handle
//Send mail function

if(empty($smtp)) die("SMTP cannot be empty!");
$this->smtp=$smtp;

if(!ereg("n$", $message))

Example of sending email using socket:

include ("./sendmail.class.php");
$mail = new sendmail();
$email = "Hello, this is a test email!";
$sendmail = new send_mail("smtp.mail.126.com","PHPBOOK",true); //Display the adjustment information
if($mail->send("XXXX@126.com", "XXXX@ 126.com", "Test SOCKET email", $email)) {
echo "Sent successfully!
";
}else{
echo "Failed to send!
";
}
?>
