#
# This script provides daily SpamFilter statistics.
#
# Re-written in python from Mailstats.pl (Perl) to conform to SME11 / Postfix / qpsmtpd log formats
# and html output added
#
# Todo
# 1. Make "yesterday" parameterised
# 2. Get data from SMEServer DB records
# 3. Other stats
# 4. Percentages for main table
# 5. Percentages and sort for Sub tables
