I think it accepts stdin, so you could pipe it zcat /var/log/maillog[0-9].gz | /usr/local/bin/spam-stats.pl > /var/tmp/spam-stats-days.rpt bourne stops [0-9], but bash can go bigger if you wanted 30 days. you can also do similar with pflogsumm, to see just the rejects stats, including avg per hour: zegrep -i "reject" /var/log/maillog[0-9].gz |\ /usr/local/bin/pflogsumm.pl -i -u 10 -h 20 \ > /some/file Len
