Incidentally, you may want to reconsider mass deletion of X-
headers; they're used as an extensible hook by many things, and it's
difficult to know in advance what may break. As a very basic example,
there's a sample recipe detailed in the procmailex manpages that uses
"X-Loop" to avoid vacation message cascading.
IMnsHO, better to remove only those headers you plan to use.
