由于我本机没有smtp,我使用smtp的时候,就是采用了网易163的 代码如下 [php]include_once ("email.php"); $sendmail = new Mail_SMTP("smtp.163.com","25","5"); $sendmail->connect('name','pass'); [/php] name是我的用户名,我的真实用户名没有写在上面 pass是我的密码 email.php是一个mail类,代码如下, 我哪里错了? 他总是提示我: Ran into problems sending Mail. Response: 550 : Invalid User 我用户应该没有错呀,我可以直接登录的~ [php]<? class Mail_SMTP { var $host = 'smtp.163.com'; // SMTP主机名 var $port = 25; // 主机的smtp端口，一般是25号端口 var $timeout = 5; // 连接主机的最大超时时间　 var $debug = 0; // 做为标识，是否在调试状态，是的话，输出调试信息 var $showerr = true; var $handle; function Mail_SMTP($server = 'smtp.163.com', $port = 25, $time_out = 5){ $this ->host = $server; $this ->port = $port; $this ->timeout = $time_out; return true; } function errmsg($err,$show=false){ if ($this->showerr || $show){ echo $err."
