In accordance with GDPR, processing of personal data must be done in a secure manner that includes protection against unauthorized or unlawful processing as well as against accidental loss, deletion, or damage. Personal identifiable information (PII) including email addresses, IP addresses, and possibly even email contents may be found in forensic reports, which are extensive descriptions of email communications and related metadata.

Due to GDPR, a lot of mailbox providers have stopped issuing forensic reports or substantially reduced the amount of PII they can contain in these reports to maintain compliance. To reduce the amount of PII that is disclosed, several providers, for instance, now transmit aggregated reports rather than in-depth forensic reports.

The absence of forensic reports might make it more challenging to locate and fix issues because they are a crucial tool for understanding and resolving email delivery problems. To guarantee that personal data is protected in compliance with GDPR and other privacy laws, it is crucial to strike a balance between the need for privacy and the need for knowledge.

It's crucial to keep in mind that even if your DMARC configuration calls for forensic reports, you might never get them because of GDPR's worries about privacy. Mailbox providers may elect not to submit forensic findings because they are wary of disclosing personally identifiable information (PII). It's important to be aware of this restriction and to think about other measures to monitor and enhance the security and deliverability of your emails.
