php指定smtp服务器发邮件

回复 收藏
以前一直都使用linux服务器自带的sendmail服务，但是这个很不稳定，经常发送不出去，所以想到使用php程序指定smtp服务器来发送邮件。把下面的代码保存到一个php文件内，例如 mail.php
  1. <?php
  2. class Smtp
  3. {
  5.     /* Public Variables */
  6.     var $smtp_port;
  7.     var $time_out;
  8.     var $host_name;
  9.     var $log_file;
  10.     var $relay_host;
  11.     var $debug;
  12.     var $auth;
  13.     var $user;
  14.     var $pass;
  15.     /* Private Variables */
  16.     var $sock;
  17.     /* Constractor */
  19.     function Smtp($relay_host = "", $smtp_port = 25,$auth = false,$user,$pass)

  269. //$smtp->debug = TRUE;//是否显示发送的调试信息
  270. $smtp->sendmail($smtpemailto, $smtpusermail, $mailsubject, $mailbody, $mailtype);
  271. ?>
要想发邮件的话，运行
php  mail.php  "邮箱主题写在这里" "/tmp/test.txt"
其中，/tmp/test.txt 内容为邮件内容。
