PHP自定义SMTP邮件功能返回ERROR fputs发送字节失败errno = 32管道损坏

Question

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nexts php错误:

注意:fputs()[function.fputs]:发送8192个字节失败,错误为errno = 32第165行/cakeapp/trunk/app/controllers/components/email.php中的管道损坏

注意:fputs()[function.fputs]:发送49个字节失败,errno = 32第169行/cakeapp/trunk/app/controllers/components/email.php中的管道损坏

注意:fputs()[function.fputs]:发送6个字节失败,errno = 32在第182行的/cakeapp/trunk/app/controllers/components/email.php中断管

我在谷歌搜索了一些建议,但我找到的信息,谈到了与连接超时相关的问题!

任何人都可以提出解决这个问题的方法吗？

我有同样的问题,并通过将协议设置为'邮件'找到解决方案(当然,这不是总是你需要使用"邮件"作为协议的情况,我在另一个网站使用"smtp"作为协议,并且工作正常,但我为其他网站复制和粘贴的相同代码并没有工作,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
