Along similar lines, any well-written Procmail recipe which redirects
mail typically checks for, or adds, an "X-Loop" header before
forwarding anything.
If the "editheader" Sieve extension gets implemented, then a well-
written sieve script should be able to do the same type of thing.
To me this seems a bit more sane than expecting lmtp or sieve to
accomplish it automatically.
