# NOTE: we cat mail.log.1 and mail.log to pick up anything after a log rotate
# then, pass the output to pflogsumm with the "yesterday" parameter, then use mailx
# to send it to the postmaster alias.
#
# will emit an error to stderr if mail.log.1 does not exist, in which case it will
# only get stats from mail.log

# This file (or a link) should be placed in /etc/cron.daily on a Debian system
