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
