It's written in Perl and runs daily from cron to send you an email summary of Postfix activity.  You might need to tweak the configs, I installed it decades ago when I started running my mail server, so I forget the details.

I also use pflogsumm. I don't remember if I had to tweak anything to
get it to run, but that was a decade ago when I switched from qmail to
postfix so I suppose it's possible.

My main way of running it is to report on all the mail logs I have,
which is typically about a month's worth. I do that by running

zcat -f /var/log/mail.log* | pflogsumm | less

I still have all the machinery in place to run my own mail server at
home. It doesn't get much use since I switched to Fastmail, mostly
just forwarding internal email reports (cronjobs, etc.) from my
Linode. It's still nice to run pflogsumm periodically just to make
sure nothing seems out of the ordinary.
