[9fans] multipart/alternative encoded emails?

[Robert Raschke <rrplan9@tombob.com>]

Hi,

before I embark on learning a lot about upas/fs (which, I guess, would
arguably be a good thing to do regardless) I thought I'd ask if anyone
has had any thoughts on how to handle multipart/alternative encoded
emails?

I have been receiving more and more emails of the following ilk:

> From: somebody
> To: me
> Subject: Your Newsletter 31/05/2005
> Date: Thu, 31 Mar 2005 14:10:02 +0100
> MIME-Version: 1.0
> Content-Type: multipart/alternative;
> 	boundary="----=_NextPart_09891202_825CBB53C42C97F2"
> 
> ------=_NextPart_09891202_825CBB53C42C97F2
> Content-Type: text/plain; charset="us-ascii"
> Content-Transfer-Encoding: 7bit
> Content-Disposition: inline
> 
> 
> 
> ------=_NextPart_09891202_825CBB53C42C97F2
> Content-Type: text/html; charset="iso-8859-1"
> Content-Transfer-Encoding: quoted-printable
> Content-Disposition: inline
> 
> [lotsa html]

That's an empty first part!

I have attempted to alert the senders to the wrongness of their
approach, but never got any replies.  So, I am trying to figure out
how alternative content emails could fit into upas/fs.

(Hmm, a cursory glance at the upas/fs sources would lead me to believe
that I should see the alternatives just like regular multipart/mixed
attachments.  Strange.)

Thanks for any pointers,
Robby
