宝塔搭建 phpmailer 邮件无法发送


PHPMailer邮件类使用错误分析

一，没有定义发送邮箱$mail->From或格式不正确，错误提示：Language string failed to load: recipients_failed test@test.com，注意，这个配置一定要正确，而且是正确的邮箱

二，没有定义邮件服务主机$mail->Host或连接失败，错误提示：Language string failed to load: connect_host

三，没有定义发送邮箱$mail->AddAddress或邮箱格式不正确，错误提示：Language string failed to load: provide_address

四，没有定义邮箱发送用户名$mail->Username，错误提示：Language string failed to load: connect_host

五，没有定义邮箱发送密码$mail->Password，错误提示：Language string failed to load: connect_host，这类错误非常明显，一般都是邮箱服务器配置不正确不能边接。

六，邮件正文编码，如果发送HTML邮件，需要定义正确的编码格式和字符，发送GBK邮件如下：
$mail->IsHTML ( true ); 是否支持HTML邮件
$mail->CharSet = "GB2312"; 字符设置
$mail->Encoding = "base64"; 编码方式
配置后可直接发送HTML邮件，如下：

  1.     <html>
  2.     <head>
  3.     <meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
  4.     <title>PHPMailer邮件测试</title>
  5.     </head>
  6.     <body>
  7.     <div>PHPMailer邮件类使用错误分析</div>
  8.     </body>
  9.     </html>

七，学会正确使用错误提示$mail->ErrorInfo查看邮件错误，可直接查找问题。

使用PHPMailer邮件类发送邮件使用非常简单，基本配置如上所示，在使用过程中正确了解错误提示，并及时了解错误原因，对于正确使用PHPMailer邮件类来说非常重要。

==========================================================================

这几天做mail群发，碰到不少问题。一些常见的错误网上很多但没有答案，靠自己不断的尝试终于OK了～这里把几个常见的问题列出来做为工作笔记！
     要做发送邮件功能，首先要明白邮件收发的原理，引用网友一段话比较容易懂：

  1. 在Internet上将一段文本信息从一台计算机传送到另一台计算机上，可通过两种协议来完成，即SMTP(Simple Mail Transfer Protocol，简单邮件传输协议)和POP3(Post Office Protocol，邮局协议3)。SMTP是Internet协议集中的邮件标准。在Internet上能够接收电子邮件的服务器都有SMTP。电子邮件在发送前，发件方的SMTP服务器与接收方的SMTP服务器联系，确认接收方准备好了，则开始邮件传递；若没有准备好，发送服务器便会等待，并在一段时间后继续与接收方邮件服务器联系。这种方式在Internet上称为“存储——转发”方式。POP3可允许E-mail客户向某一SMTP服务器发送电子邮件，另外，也可以接收来自SMTP服务器的电子邮件。换句话说，电子邮件在客户PC机与服务提供商之间的传递是通过P0P3来完成的，而电子邮件在 Internet上的传递则是通过SMTP来实现。

如果觉得不够清楚的话，则引用网上的一张图来解释吧:

有关phpmailer的介绍可以参考官网：http://phpmailer.codeworxtech.com/

常见异常：

1.SMTP Error: Could not authenticate.

   这个是因为smtp验证没通过，就是smtp server 的用户名和密码不正确了

  1.     $mail->Username    = "smtp@163.com";     // SMTP server username   
  2.     t;Password    = "******";     
  3.  
  4. $mail->Username = "smtp@163.com"; // SMTP server username $mail->Password = "******";

2.Could not execute: /usr/sbin/sendmail

    这是因为 

  1.     $mail->IsSendmail();  // tell the class to use Sendmail   
  2.  
  3. $mail->IsSendmail(); // tell the class to use Sendmail

   去掉上面的代码就ok了！(PHP同理)

3.关于phpmailer发送邮件产生中文乱码问题

环境一：在普通环境，即标题内容等含中文的内容是在脚本中加上去的，或从文本中获取的，只需要进行如下操作(网上有很多)：
   修改class.phpmailer.php中的EncodeHeader函数，改为：

  1.     public function EncodeHeader($str, $position = 'text', $pl = 0) {   
  2.        $x = 0;   
  3.        if ($pl){return "=?".$this->CharSet."?B?".base64_encode($str)."?=";}   
  4.  
  5. public function EncodeHeader($str, $position = 'text', $pl = 0) { $x = 0; if ($pl){return "=?".$this->CharSet."?B?".base64_encode($str)."?=";}

再改下使用这个函数的一段： 

  1.     if($this->Mailer != 'mail') {   
  2.           $result .= $this->HeaderLine('Subject', $this->EncodeHeader($this->SecureHeader($this->Subject),'text',1));   
  3.          }  
  4.  
  5. if($this->Mailer != 'mail') { $result .= $this->HeaderLine('Subject', $this->EncodeHeader($this->SecureHeader($this->Subject),'text',1)); }

当然编码设置也不能少了： 
  1.     $mail->CharSet="utf-8";   
  2.            $mail->Encoding = "base64";  
  3.  
  4. $mail->CharSet="utf-8"; $mail->Encoding = "base64";

环境二：从excel中提取内容然后再发送excel中的内容给用户，这个折腾了我好久。最终找到解决办法了。最关键的地方是：excel中的编码是html格式的unicode，所以得使用下面这个函数将其转化为utf8,这个帖子的最后回复的人帮了我，谢谢他!帖子地址是：http://www.phpchina.com/bbs/viewthread.php?tid=111554 

  1.     private function uc2html($str)   
  2.        {   
  3.         $ret = '';   
  4.         for( $i=0; $i<strlen($str)/2; $i++ )   
  5.          {   
  6.             $charcode = ord($str[$i*2])+256*ord($str[$i*2+1]);   
  7.             $ret .= '&#'.$charcode.';';   
  8.           }   
  9.         return mb_convert_encoding($ret,'UTF-8','HTML-ENTITIES');   
  10.        }   
  11.         
  12.  
  13. private function uc2html($str) { $ret = ''; for( $i=0; $i<strlen($str)/2; $i++ ) { $charcode = ord($str[$i*2])+256*ord($str[$i*2+1]); $ret .= '&#'.$charcode.';'; } return mb_convert_encoding($ret,'UTF-8','HTML-ENTITIES'); }

  14.     $body              = preg_replace('/\\\\/','', $body); //Strip backslashes   
  15.   
  16.     $mail->IsSMTP();                           // tell the class to use SMTP   
  17.     $mail->SMTPAuth    = true;                  // enable SMTP authentication
