Actually, everyone in Belgium using proxmail would be obligated to do that, a lot smaller providers like myself probably ignore it though.Not really, for such a use case you need to implement a powerful log server where you can store this huge amount of logs.
yes, if you syslogs are availabe for 30 days, you can also query them via the message tracking (check Debian howto for changing the log rotation)So, for my own comfort, I'd like a retention of at least a month in the message center. If I change the logrotation, it will be visible in tracking center?
Sorry for the noob question, but how can I increase the limit?The tracking center is a front-end to the syslog and the syslog files are available for 7 days, just standard Debian Linux.
If you want to store gigabytes of logs from every day for 2 years, you need a huge server. You will find a lot of tools exactly for this task.
Do I have to restart sth later?As posted above: Increase rotate count at /etc/logrotate.d/rsyslog on /var/log/syslog
However, ensure that longer logging comply as well with GDPR
This setting seems to be outside the template system. I also won’t believe, you need to restart anything to get it running.Do I have to restart sth later?
And if I will update my PMG, do I have to change again that setting? Can I do sth like a custom file?
ps: Damn, I hate GDPR :/
Yes and no, GDPR doesn’t say anything about logging but says many things about processing personal data and they are also processed in logs. GDPR then also says many things about storage limitation. So you can‘t read anything directly but the data protection supervisory bodies like to reduce the log files storage, if containing personal data and it does: sender, recipient, ...GDPR doesn't say nothing about logging. But could be a law specifically in your country, and in this case you must be follow.
