PHP smtp Send mail

PHP sends mail through SMTP through a class SMTP The code to send the message is as follows: Require_once ' smtp.php '; ########################################## $smtpserver = "smtp.sina.com";//SMTP server $smtpserverport = 25;//SMTP Server port $smtpusermail = "god_chen@sina.com"; user mailbox for//SMTP server $smtpemailto = "45323333@qq.com";//Send To whom $smtpuser = "name"; user account for//SMTP server $smtppass = "123456"; user password for//SMTP server $mailsubject = "Chinese";//Message subject $mailbody = " Chinese Can muddy the new year feeling under test ";//message content $mailtype = "HTML";//Message Format (html/txt), TXT as text mail ########################################## $SMTP = new SMTP ($smtpserver, $smtpserverport, True, $smtpuser, $smtppass);//A true in this indicates that authentication is used, otherwise no authentication is used. $SMTP->debug = false;//whether to display debug information sent $smtp->sendmail ($smtpemailto, $smtpusermail, $mailsubject, $mailbody, $mailtype) Copy Code The source code for the SMTP class is as follows: Class SMTP { /* Public Variables */ var $smtp _port; var $time _out; var $host _name; var $log _file; var $relay _host; var $debug; var $auth; var $user; var $pass; /* Private Variables */ var $sock; /* Constractor */ function smtp ($relay _host = "", $smtp _port = +, $auth = False, $user, $pass) { $this->debug = FALSE; $this->smtp_port = $smtp _port; $this->relay_host = $relay _host; $this->time_out = 30; is used in Fsockopen () $this->auth = $auth;//auth $this->user = $user; $this->pass = $pass; $this->host_name = "localhost"; is used in HELO command $this->log_file = ""; $this->sock = FALSE; } /* Main Function */ function SendMail ($to, $from, $subject = "", $body = "", $mailtype, $cc = "", $BCC = "", $additional _headers = "") { $mail _from = $this->get_address ($this->strip_comment ($from)); $body = Ereg_replace ("(^| ( \ \ \)] (\) "," \1.\3 ", $body); $header = "mime-version:1.0\r\n"; if ($mailtype = = "HTML") { $header. = "content-type:text/html\r\n"; } $header. = "To:". $to.
