Examples

Produce a report of previous day's activities:

   pflogsumm.pl -d yesterday /var/log/maillog

A report of prior week's activities (after logs rotated):

   pflogsumm.pl /var/log/maillog.0

What's happened so far today:

   pflogsumm.pl -d today /var/log/maillog

Crontab entry to generate a report of the previous day's activity
at 10 minutes after midnight.

   10 0 * * * /usr/local/sbin/pflogsumm -d yesterday /var/log/maillog
   2>&1 |/usr/bin/mailx -s "'uname -n' daily mail stats" postmaster

Crontab entry to generate a report for the prior week's activity.
(This example assumes one rotates ones mail logs weekly, some time
before 4:10 a.m. on Sunday.)

   10 4 * * 0   /usr/local/sbin/pflogsumm /var/log/maillog.0
   2>&1 |/usr/bin/mailx -s "'uname -n' weekly mail stats" postmaster

The two crontab examples, above, must actually be a single line
each.  They're broken-up into two-or-more lines due to page
formatting issues.
