I know this more of a Linux question than Zimbra, but maybe some of you have already done it and can help. I'd like to keep more versions of the /var/log/maillog and /var/log/zimbra.log, to e exact 36 days. So I changed the logrotate conf:
rotate 36 # Keep the last 36 days
create 0644 zimbra zimbra
killall -HUP syslogd 2> /dev/null || true
su - zimbra -c "/opt/zimbra/bin/zmswatchctl restart" > /dev/null 2>&1 || true
But this just doesn´t want to work! Any ideas on that one?
