(poss offtopic) How to 'not' demime a specific list subscriber

  hello Nick or anyone else,

>I've been grappling around through my lack of perl and related 
>expression understanding and have now reached the point where I have 
>somehow achieved my recent quest of trying to use the advertising sig 
>removal to remove old list footers.
>
>Now, I have to somehow find a way to demime all subscribers of a 
>specific list except for one WebTV subscriber. I have so far tried to 
>set the $::EXPAND_MULTIPART_RFC822_SECTION variable to either 0 or 1 but 
>both are not appropriate. This is because one option removes any reply 
>that he is referring to, and the other results in full headers appearing 
>in the demimed mail.
>
>I've seen a reference to WebTV in the demime file's comments, and I've 
>also seen the comments I've pasted below relating to setting my sendmail 
>alias, but I simply can't seem to think of how to set things up so the 
>WebTV person's mails by-pass demime. I've been thinking of somehow 
>catching his mails before they reach the standard alias, then maybe use 
>another mailing list to somehow merge his posts with the other demimed 
>posts, but am stumped as to how to set my CPanel filters etc to achieve 
>this without compromising the headers in the main list. A further 
>possible complication is that he is also subscribed to another list 
>using his same email address, so I can't consider piping all of his 
>posts sent to my domain to a single list specific destination.

>In case it helps in any advice you can give, here is the alias line I am 
>currently using to successfully demime all posts and then pipe to my 
>mail manager program's cron:
>
>test@mydomain.com: |/home/cpaneluser/www/demime.pl 
>"|/home/cpaneluser/www/mailgust/dbcron.pl 11"

>By the way, I don't have unix command line access to my webspace. I use 
>CPanel.
