As the message suggests, the DISCARD action is not implemented for
before-queue content filters.
Actually, DISCARD could be implemented, but other actions such as
FILTER and REDIRECT definitely cannot, because they require an
action by the post-filter MTA, and there is no way request that
action through an SMTP-based filter.

Maybe the before-queue filter can discard the message instead.
