[imp] Mime viewer help

[John H. Bennett III]

Hello,

I am receiving a lot of emails that state. "show this html in a new  
window." I'm trying to figure out how to get these messages to display  
inline, if possible.  I can see the disclaimer text, but none of the  
body text.  Looking at the mime information, I see this:
MIME-Version: 1.0
Content-Type: multipart/alternative;
	boundary="----_=_NextPart_001_01C932BE.4480C18F"

I have also worked with mime_viewers.php in both horde and imp, but I  
don't seem to be able to correct the current behavior.  In this case,  
when someone responds to this email, the mime type changes to:
Content-Type: text/plain; charset="UTF-8"

and all displays in-line.

Is there anything I can do to correct this, or is this the expected behavior?

Not that I want to, but I haven't read through the various mime RFC's,  
located here: http://www.iana.org/assignments/media-types/multipart/.

Thanks,

John
