This tutorial will show you how to set up your log statistics to be mailed to you every night so you know what is happening with your Postfix Mail Server.

Set up a cron job so that it will run at 11:55 PM, just before midnight as you want to get all of the logs for that day.  Be sure to give enough time for the script to run before the next day.  Here is the line to use if you have install pflogsumm at /usr/pflogsumm, see this article for installation.

As root run:

crontab -e

Now add this line with your email at the end.  Note the \ which indicates a line break.

55 23 * * * /usr/pflogsumm/./pflogsumm.pl -u 5 -h 5 –problems_first -d today \
/var/log/maillog | mail -s “PostFix Report  `date`” \someemail@somewhere.com

Here is an example
