The code to send the message is as follows:

function SendMail ($to, $title, $content) {//Introducing Phpmailer's core file using require_once contains warnings to avoid duplicate definitions of Phpmailer classes require_once ("./     Class.phpmailer.php ");    Require_once ("./class.smtp.php");    Instantiate the Phpmailer core class $mail = new Phpmailer ();    Whether to enable debug for SMTP debugging development environment It is recommended to turn on the production environment comments off can be turned off by default Debug debug mode $mail->smtpdebug = 1;    Use SMTP authentication to send mail $mail->issmtp ();    SMTP needs authentication This must be true $mail->smtpauth=true;    The server address of the link QQ domain mailbox $mail->host = ' smtp.qq.com ';    Set the login authentication using SSL encryption $mail->smtpsecure = ' SSL ';    Set the SSL connection to the SMTP server's remote server port number, the previous default is 25, but now the new seems to be unavailable optional 465 or 587 $mail->port = 465;    Set SMTP Helo message header This optional content arbitrary $mail->helo = ' Hello smtp.qq.com Server ';    Setting the sender's host domain is optional by default to localhost content, it is recommended to use your domain name $mail->hostname = ' http://www.dest.cn ';    Set encoding for sent messages optional GB2312 I like Utf-8 said UTF8 in some clients will be garbled $mail->charset = ' UTF-8 '; Set the sender name (nickname) any content that displays the sender's name before the sender's email address of the recipient's message $mail->fromname = ' TEST lyf3312 '; Sender Everyone name//SMTP login account here fill in the string format QQ number can be $mail-&GT    Username = ' 924634623@qq.com '; The password for the SMTP login uses the generated authorization code (just the latest authorization code that you saved) $mail->password = ' Wrgomczwlipobaib ';    Wrgomczwlipobaib//Set the sender's email address here to fill in the "sender's mailbox" mentioned above $mail->from = ' 924634623@qq.com ';     Whether the message body is HTML-encoded note here is a method that is no longer a property of true or False $mail->ishtml (true); To set a recipient's mailbox address this method has two parameters the first parameter is the recipient's mailbox address the second parameter is a different mailbox system that is set to that address.

";} else{echo "failed to send mail! ";}

Strangely, when you turn off SSL and switch to port 25, you can send mail, but you will send out the message.

What's the reason AH ah ah ah ah ah oh ah ah??
