Which is best Postfix Log analyzer?

Inspired by aimfeld, pflogsumm is really better and simpler to use:

Just install it using following commands. For Debian/Ubuntu (https://packages.debian.org/sid/pflogsumm):

apt-get install pflogsumm

For RedHatLinux/RHEL, CentOS, Fedora:

yum install postfix-pflogsumm

Example usage, get today's summary by:

pflogsumm -d today /var/log/mail.log
