I'm already patching sympa to meet various needs - its in cvs and I just 
have to merge via the vendor branch whenever you release a new version. But 
it would be nice not to have to modify wwwsympa anymore than necessary. I 
think its  a good feature for sympa to have to be able to store valid 
attachments in the archives - at least for controlled content posting as in 
the newsletter style scenarios.

I dont need them stored elsewhere - the archive directory is fine. And thats 
where they go in my current mhonarc setup. The problem is that wwsympa cant 
deliver the attachment files for viewing ( generating the tt2 error 
instead). The thing is, both the archived, htmlified email body and is the 
corresponding attachment are in the same directory, but do_arc can only 
deliver the message (embedded via the main.tt2 template) but not the 
standalone html file in the attachment (which isnt meant to be viewed 
inside the wwsympa interface, but either in its own window or at least 
inside a frame - i.e. needs to be delivered as-is .

so 
http://test.site.com/sympa/arc/testlist/2006-10/msg00001.html
works, but not the url for its attachment which is in the same physical 
directory :
 http://test.site.com/sympa/arc/testlist/2006-10/htmlpA3GuSYmpG.html

Essentially, the attachments sent to the list in question, being copies of 
web page content that are reconfigured to be viewed offline, are full html 
documents with embedded stylesheets. They cannot render properly if left 
inline in the default mhonarc setup on sympa. I want them to be stored in 
the sympa archive along with the email they came with and to be accessible 
via a link in the archived page. Using mhonarcs config options I can do 
everything but get wwwsympa to deliver the stored attachment document. I 
dont mind setting up a web server alias to deliver the archive files (say 
like  http://test.site.com/sympa-archives/ ) but I havent been able to 
figure out how to get mhonarc to generate the appropriate link to the 
attachment file on the archive page ( e.g.
http://test.site.com/sympa-archives/testlist/2006-10/htmlpA3GuSYmpG.html ). 
The closest I can get is :
http://test.site.com/sympa-archives/testlist/htmlpA3GuSYmpG.html 

A dynamic part of the path - the month directory - is a runtime value and 
cant be embedded in the mhonarc_resources config as far as I can tell. It 
appears to be a current limitation in mhonarc. The examples given on the 
mhonarc site only deal with a single url path for ALL attachment files it 
will ever create. Of course sympa creates a new subdir for each month ...
