Matthias,

Looking at the code, I see get_token() calling the flex parser to get
tokens and then discarding what's found (if the mime type indicates
that's what should be done).  Grepping the code for MIME_APPLICATION
doesn't reveal code to skip parsing attachments.  I've not examined the
code too deeply, hence might have missed something relevant.

Looking in lexer_v3.l there's an interesting bit of code:

  type = get_content_type();
  ...
  switch (type) { 
     case MIME_TEXT_HTML: BEGIN HTML; break;
     case MIME_MESSAGE:   yy_set_state_initial(); break;
     default:             BEGIN TEXT;

Adding:

     case MIME_APPLICATION:  BEGIN SKIP; break;

and 

   <SKIP>.   ; /* ignore */
   <SKIP>^$  { BEGIN TEXT };

might be interesting (or something like it).
