Blog by email posts blank in 2.5.1 w/ HTML email

I suspect that the problem lies in this section of wp-mail.php:

139    if ($content_type == 'multipart/alternative') {
140 	        $content = explode('--'.$boundary, $content);
141 	        $content = $content[2];
142 	        $content = explode('Content-Transfer-Encoding: quoted-printable', $content);
143 	        $content = strip_tags($content[1], '<img><p><br><i><b><u><em><strong><strike><font><span><div>');

Gmail sends out HTML mail as a multipart/alternative, however it doesn't have the 'Content-Transfer-Encoding: quoted-printable' header. This leaves $content[1] empty, which results in a post with a title, but no body.

A different solution is needed to remove the headers from the multipart message. I tried doing the following and it seems to be working, but there is probably a better way to detect this.

142 	        $content = explode('\n\n', $content);

A fix to this section of code will probably help most people that are having problems with blank posts coming from email.

Hi,

i changed the line in wp-mail.php, but still the post show up blank.

Maybe this can help ..

Go to line 139, and paste this above it.

function rheaders($string) {
	$headers = array(
		"/Content\-Type\: text\/html\; charset\=UTF\-8/i",
		"/Content\-Transfer\-Encoding\: 7bit/i",
		"/Content\-Disposition\: inline/i"
		);
	return preg_replace($headers, '', $string);
}

Now edit this line

$content = explode('Content-Transfer-Encoding: quoted-printable', $content);

By:

$content = rheaders($content);

Maybe you need to change the rheaders function to whatever the headers of the email are.

This helped me get my issues fixed with a couple of caveats. If multiple messages are waiting to be processed, the rheaders function gets redeclared. I moved the function outside the message loop and fixed that problem.

Also, the line following the call to rheaders needs to be changed because rheaders returns a single string and not an array. Here's what worked for me; I took the original strip_tags line:

  $content = strip_tags($content[1],'<img><p><br><i><b><u><em><strong><strike><font><span><div>');

and changed it to:

  $content = strip_tags($content, '<img><p><br><i><b><u><em><strong><strike><font><span><div>');

I did need to add the following line to the headers array in order to handle Gmail's rich formatting.

  "/Content\-Type\: text\/html\; charset\=ISO\-8859\-1/i",

AOL mail comes in with yet another encoding, which I think can be fixed by adding:

  "/Content\-Type\: text\/html\; charset\=us\"\-ascii\"/i",

I suppose a more robust regexp would be helpful here; something that accepts text\html regardless of the encoding. I think there is a newline that could be matched at the end of the line, but I'm not sure how to go about that in PHP.
