David pointed me to some mistake, I have to apologize.

Drop the E from the first reipe. In my .procmailrc this makes sure
that good mail will not be deleted (say, someone from Japan sends a
mail in his charset, using ASCII only).

Secondly, the \/ which is missing in the second rule anyways, is
without effect here (does not hurt, though), it puts the match into
$MATCH.
