Should I rotate cpgreylistd.log ?

[GoWilkes]

I see that it doesn't rotate by default, but mine is 130M... is there a reason to NOT rotate it?

Hey there,

If your log is growing in size, it is a good idea to rotate or compress the log.

This should work for you if you want to create a new configuration and rotate the log:

logrotate(8) - Linux man page

logrotate is designed to ease administration of systems that generate large numbers of log files. It allows automatic rotation, compression, removal, and ...

linux.die.net

Create the file:

vi /etc/logrotate.d/greylisting

Copy the code:

/usr/local/cpanel/logs/cpgreylistd.log {
    rotate 3
    compress
    missingok
    notifempty
    sharedscripts
    postrotate
        /scripts/restartsrv_cpgreylistd
    endscript
}

Verify your configuration which will run the new greylisting log rotate file we created.

/usr/sbin/logrotate -f /etc/logrotate.conf

And then we can confirm the file was rotated and compressed.

[[email protected] public_html]# ls -lah /usr/local/cpanel/logs/cpgreylistd*

-rw-------. 1 root root 45K Oct 29 19:55 /usr/local/cpanel/logs/cpgreylistd.log-20201029.gz

I hope this helps.
