# Wrapper for qmail-queue that filters messages before injecting
#   into the queue.
#
# Using this wrapper, executable filters:
# * Must be placed in @PKG_SYSCONFDIR@/filters
# * Must have filenames matching "qfilter-*"
# * Will be executed with no arguments
# * Will be executed in sort(1) order
#
# To use this script to filter messages arriving via SMTP, set the
# QMAILQUEUE environment variable in tcp.smtp like so:
#
# :allow,QMAILQUEUE="@PREFIX@/bin/qmail-qfilter-queue"
#
# Then rebuild the cdb.
