电子邮件未发送“发现多行”错误[重复]

Question

下面是我的电子邮件发送脚本的代码，一年了同样的代码运行良好，但现在它没有发送任何电子邮件，请帮我解决这个错误

消息：mail()：在 Additional_header 中发现多个或格式错误的换行符

$encoded_content = chunk_split( base64_encode( $variables['pdfFileContents'] ));

$uid = md5( time() );

$fileName = str_replace( " ", "_", $variables['emailContains'] );
$fileName .= ".pdf";

////// attachment header ///////////////////////////////
$headers = array();
$headers[] = "MIME-Version: 1.0";
$headers[] = "From: cashxcash.com<{$sender}>";
$headers[] = "Content-Type: multipart/mixed; boundary=\"{$uid}\"";
$headers[] = "This is a multi-part message in MIME format.";
$headers[] = "--{$uid}";
$headers[] = "Content-type:text/plain; charset=iso-8859-1"; // Set message content type
$headers[] = "Content-Transfer-Encoding: 7bit";
$headers[] = ""; // Dump message
$headers[] = "--{$uid}";
$headers[] = "Content-Type: application/octet-stream; name=\"{$fileName}\""; // Set content type and file name
$headers[] = "Content-Transfer-Encoding: base64"; // Set file encoding base
$headers[] = "Content-Disposition: attachment; filename=\"{$fileName}\""; // Set file Disposition
$headers[] = $encoded_content; // Dump file
$headers[] = "--{$uid}--"; //End boundary

return mail(
    $reciever,
    "{$variables['emailContains']} Report from Cashxcash!",
    "", 
    implode("\r\n", $headers)
);

Answer 1

您必须确保主机上的 MTA（邮件传输代理）不是 QMAIL，因为众所周知，它会将 LF 替换为 CRLF。 然后，您必须将所有标题移动到mail() 的第 4 个参数中，并将您的电子邮件正文移动到 mail() 的第 3 个参数中。像这样的：

$encoded_content = chunk_split( base64_encode( $variables['pdfFileContents'] ));

$uid = md5( time() );

$fileName = str_replace( " ", "_", $variables['emailContains'] );
$fileName .= ".pdf";

$headers = array();
$headers[] = 'MIME-Version: 1.0';
$headers[] = 'From: cashxcash.com<'.$sender.'>';
$headers[] = 'Content-Type: multipart/mixed; boundary="'.$uid.'"';

$body = 'This is a multi-part message in MIME format.

--'.$uid.'
Content-type:text/plain; charset=iso-8859-1
Content-Transfer-Encoding: 7bit

--'.$uid.'
Content-Type: application/octet-stream; name="'.$fileName.'"
Content-Transfer-Encoding: base64
Content-Disposition: attachment; filename="'.$fileName.'"

';
$body.= $encoded_content; // Dump file
$len = strlen($encoded_content);
if(!($encoded_content{$len-2} == "\r" AND $encoded_content{$len-1} == "\n")) $body.= "\r\n";
$body.= '--'.$uid.'--'; //End boundary

return mail($reciever,$variables['emailContains'].' Report from Cashxcash!',$body, implode("\r\n", $headers) );
