我编写了下一个自定义 PHP 函数来通过 SMTP 邮件服务器发送邮件。

function send($format = 'text'){

    $smtpServer  = 'mail.mymailserver.com.mx';
    $port        = '25';
    $timeout     = '60';
    $username    = 'myuser';
    $password    = 'mypassword';
    $localhost   = 'www.mydomain.com.mx';
    $newLine     = "\r\n";

    $smtpConnect = fsockopen( $smtpServer, $port, $errno, $errstr, $timeout );

    fputs( $smtpConnect,'AUTH LOGIN'.$newLine );
    fputs( $smtpConnect, base64_encode( $username )  . $newLine    );
    fputs( $smtpConnect, base64_encode( $password )  . $newLine    );
    fputs( $smtpConnect, 'HELO '       . $localhost  . $newLine    );
    fputs( $smtpConnect, 'MAIL FROM: ' . $this->from . $newLine    );
    fputs( $smtpConnect, 'RCPT TO: '   . $this->to   . $newLine    );

    if( !empty( $this->cc ) ){
        fputs( $smtpConnect, 'RCPT TO: '   . $this->cc   . $newLine    );
    }

    if( !empty( $this->bcc ) ){
        fputs( $smtpConnect, 'RCPT TO: '   . $this->bcc  . $newLine    );
    }

    fputs( $smtpConnect, 'DATA'        . $newLine                  );

    fflush( $smtpConnect );

    $raw  = "";
    $raw  = @fread( $smtpConnect, 255 ) . "@";
    $raw .= @fread( $smtpConnect, 255 );

    fputs( $smtpConnect, 'To:     '  . $this->to . $newLine        );
    fputs( $smtpConnect, 'From:   <' . $this->from .'>' . $newLine );
    fputs( $smtpConnect, 'Subject:'  . $this->subject . $newLine   );

    $format = 'html';

    if( $format == 'text' ){

        $headers  = "Content-Type: text/plain; charset=\"iso-8859-1\"" . "\r\n";
        $headers .= "Content-Transfer-Encoding: 7bit" . "\r\n";

        $message  = $this->bodyText();

        fputs( $smtpConnect, $headers   . $newLine  . $newLine       );
        fputs( $smtpConnect, $message   . $newLine  . '.' . $newLine );

    }else{

        $random_hash = md5(date('r', time()));

        $headers  = "Content-Type: multipart/alternative; boundary=\"PHP-alt-".$random_hash."\"\r\n";
        $headers .= "--PHP-alt-" . $random_hash . "\r\n";
        $headers .= "Content-Type: text/plain; charset=\"iso-8859-1\"" . "\r\n";
        $headers .= "Content-Transfer-Encoding: 7bit" . "\r\n";

        $message  = $this->bodyText();

        fputs( $smtpConnect, $headers . $newLine );
        fputs( $smtpConnect, $message . $newLine );

        $headers  = "--PHP-alt-" . $random_hash . "\r\n";
        $headers .= "Content-Type: text/html; charset=\"iso-8859-1\"" . "\r\n";
        $headers .= "Content-Transfer-Encoding: 7bit" . "\r\n";

        $message  = $this->bodyHtml();

        fputs( $smtpConnect, $headers  . $newLine );
        fputs( $smtpConnect, $message  . $newLine );

        $headers  = "--PHP-alt-" . $random_hash . "--\r\n";

        fputs( $smtpConnect, $headers . '.' . $newLine  );

    }

    fputs( $smtpConnect,'QUIT'      . $newLine );

    return true;

}

该功能运行良好，但在最后几天我收到了下一个 php 错误:

注意:fputs() [function.fputs]:发送 8192 字节失败，errno=32 Broken pipe in/cakeapp/trunk/app/controllers/components/email.php on line 165

注意:fputs() [function.fputs]:发送 49 个字节失败，errno=32 Broken pipe in/cakeapp/trunk/app/controllers/components/email.php on line 169

注意:fputs() [function.fputs]:发送 6 个字节失败，errno=32 Broken pipe in/cakeapp/trunk/app/controllers/components/email.php on line 182

我在 Google 中搜索一些建议，但我找到的信息谈到了与连接超时相关的问题!

谁能提出解决这个问题的方法？

最佳答案

我遇到了同样的问题，通过将协议(protocol)设置为“邮件”找到了解决方案(当然这不是你总是需要使用“邮件”作为协议(protocol)的情况，我在另一个网站上使用“smtp”作为协议(protocol), 并且工作正常，但是我复制并粘贴到其他网站的相同代码没有工作，所以我不得不将其更改为“邮件”)。我的示例配置如下所示(用您自己的凭据替换大写单词):

'protocol' => 'mail',            
'smtp_host' => 'mail.YOUR_WEBSITE_DOMAIN.com.au',            
'smtp_port' => 25,            
'smtp_user' => 'YOUR_EMAIL_ACCOUNT@YOUR_WEBSITE_DOMAIN.com.au',            
'smtp_pass' => 'YOUR_PASSWORD_FOR_YOUR_EMAIL_ACCOUNT',            
'smtp_timeout' => 5,// The default value            
'mailtype' => 'html' //default: text
