[svlug] Virus FUD

With MH you can specify what needs to be done with a special MIME type.
For example with a perl script, I can run it or simply store it or delete it.
If no directive are specified it simply skip or display it ( as I wish )

With HTML email, if it is a multiparti/alternative email 
( same content but different formats for each of the mime parts ) you can 
specify which part you want to see ( text/ascii for example ).

With a text/html I can display it using lynx or cat or even pipe it in
a third party program.

I was wondering if the same level of flexibility is available in Mutt ?

I don't know anything that MH can not implement... or maybe one thing,
but that is not supported by mutt ( or maybe ! ): external html parts.

This is useful when you run MHonarc ( or equivalent email2html). 
The external html part
is simple to understand. I send MIME info with a URL in mime header,
then the MUA is supposed to connect ( http ) to the URL upon openning of the email.
i.e. I send an URL and not a copy of the html page. 

Currently MH support only ftp external parts....

Any idea how to implement such a feature ? 
Are external parts supported by mutt ?

 The problematic e-mail one can receive even in mutt (albeit with no
 virus exposure) might bear some careful thought.  E.g., many mutt
 installations automatically fork a copy of lynx for HTML MIME types,
 exposing you to the privacy violations previously discussed.  There
 might be other problems that don't occur to me.  
 I tend to cut those off at the pass by disabling the call to lynx and
 sticking to "raw" e-mail -- but author Scott Courtney's thoughts on the
 dangers of "active" content have merit, and deserve looking into.  (I'm
 not sure I like his candidate solution, but there are no doubt others.)
