method Four , give the socket written by the program to use the socket to send mail package class:

  1. Class sendmail{
  2. var $lastmessage; Record the last returned response information
  3. var $lastact; The last action, the string form
  4. var $welcome; Use behind helo, welcome user
  5. var $debug; Whether to display debug information
  6. var $smtp; SMTP server
  7. var $port; SMTP port number
  8. var $fp; Socket handle
  9. Send mail function
  10. function Send_mail ($smtp, $welcome = "", $debug =false) {
  11. if (empty ($SMTP)) Die ("SMTP cannot be empty!") ");
  12. $this->smtp= $smtp;

    4. $sendmail = new Send_mail ("smtp.mail.126.com", "Phpbook", true); Display information
    5. if ($mail->send ("XXXX@126.com", "XXXX@126.com", "Test socket Mail", $email)) {
    6. echo "sent successfully!
      ";
    7. }else{
