Blank Multipart email

Question

I\'m using PHP to send out a multipart/mixed message (plain text, html and attachments). However, whilst it works for most accounts, Yahoo, GMail and Sky seem to show blank

Answer 1

It may be an artifact from pasting, but try removing the blank space at the end of each boundary. (Highlight the text and you'll notice the boundaries have an extra space, but the closing boundaries-- do not)

Answer 2

Please verify whether your code is look like the following because the following code is working fine for me.

$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-Type: multipart/mixed; boundary=\"".$uid."\"\r\n\r\n";
$headers .= "This is a multi-part message in MIME format.\r\n";
$headers .= "--".$uid."\r\n";
$headers .= "Content-type:text/html; charset=iso-8859-1\r\n";
$headers .= "Content-Transfer-Encoding: 7bit\r\n\r\n";
$headers .= $msg."\r\n\r\n";    
$headers .= "--".$uid."\r\n";
$headers .= "Content-Type:application/html; name=\"".$filename."\" \r\n"; // use different content types here
$headers .= "Content-Transfer-Encoding: base64\r\n";
$headers .= "Content-Disposition: attachment; filename=\"".$filename."\"\r\n\r\n";
$headers .= $content."\r\n\r\n";
$headers .= "--".$uid."--";

Don't build your own MIME messages. use Swiftmailer or PHPMailer to do it for you.
