FHS! you should do your homework!

Apart from the obvious typo I think the set statements should be
*after* the conditions, otherwise acl_m0 will *always* be set to
those values.

So, for instance:

warn    demime = txt
         set acl_m0 = text_only


Actually, the whole thing can be rewritten as:

warn    set acl_mo = mixed


warn    demime = txt
         set acl_m0 = text_only



unless you want acl_m0 unset if there are no attachments (and the
modification in this case are trivial).
