PHP Mail Multipart Showing Blank in Yahoo

I have a multi-part email that I am sending off, I have tested it in Hotmail, Thunderbird, Outlook and Yahoo.  It works fine in all but Yahoo.  In Yahoo it is coming through but blank.  I have played with the headers a bit and if I leave the "Content-Type" blank it will come through raw.  If I included the Content-Type header it will come through blank.

I had read that the boundary in the header needed to be surrounded by double quotes so I added those, that didn't.  Here is the header from Yahoo where it is coming through blank, it looks fine to me.  Blow is the full code, I am sure I am missing something very simple but this is a real big problem.

Wow, this was a simple one and I am surprised that it wasn't answered before I figured it out.  The parsing after an echo was muffed up.

--PHP-alt-<?php echo $random_hash; ?>
Content-Type: text/html; charset="iso-8859-1"

needed to be

--PHP-alt-<?php echo $random_hash; ?>

Content-Type: text/html; charset="iso-8859-1"

The extra line break is necessary and fixes the problem, without it it is merging both lines together and thus making the boundary invalid.
