An administrator can therefore read, on the message itself, why it was delivered.

These are two services and two durations.<\/p>\n<h3>The clock chosen by the company<\/h3>\n<p>It depends on the purpose. No text sets a single retention period for an email filtering log. The framework is that of the GDPR: data is kept for as long as the purpose justifies it, and this is documented.<\/p>\n<p>A useful benchmark: for logging access to and operations on personal data processing, the CNIL recommends a period of between six months and one year, longer in certain justified cases. This recommendation is not prescriptive, and it applies primarily to access logs, not to a filtering log. It also points out that logs should not retain data beyond the period set for the data itself.<\/p>\n<p>In practice, the long retention period applies to the export, in your SIEM: that is where you set retention, access and deletion.
