[updated subject to reflect correct imp version, horde3 rc3 implied]

Yo all,

I've messed with this, and messed with this...UGH!!   I even tried to decode
what it's problem was by going through all the IMP and Horde framework code.
Man, my head hurts, that's just way complex for me tonite.

I've even read over RFC 2387 a couple times:

     ftp://ftp.ietf.org/rfc/rfc2387.txt

This has even been quite a bit of help in my quest to get this working 
properly:

     http://www.dsv.su.se/~jpalme/ietf/mhtml.html

If you have an example message source which I could look over, which 
allows for
a html attachment to open with img src's pointing to cid:<content-id> internal
MIME parts, that would be awesome.

I'm changed to the multipart/related overall mime type as well, still no luck.
I've messaged with content-disposition settings (every combination of inline
and attachement).

For the record, these look fine in Outlook, so I know I'm close.  I'm sure M$
isn't following the same [public] spec you guys are though! ;-)

Thanks for the help, I'm going to bed!! :)
