I have the same problem.

but I'm not sure about the "postfix start/stop" pattern.
my mail.log has no such words.

chchang@mx:~/postfix-log-parser_linux_amd64$ sudo cat /var/log/mail.log|grep postfix-script
chchang@mx:~/postfix-log-parser_linux_amd64$

I run into the same problem. But mine also does not have "postfix start/stop" anywhere.

used this repository but it seems it converts the timestamp value to 0000 in the year field. Any idea what needs to be done for this'
