For a sender doing a few thousand messages a month, with clean SPF and aligned DKIM and no known third-party senders, what triggers the step to quarantine and then reject? A fixed number of rua reports, a quiet period with no unexplained failures, a business requirement, or something else? And how much weight do you give the risk of an unseen legitimate flow breaking on the way?
There are situations where enforcing DMARC will reject legitimate mail (e.g. mailing lists/forwarders that do not rewrite both From: and MAIL FROM:).
Do the reports you receive indicate such failures? If so, is it a problem for you if the messages are rejected here? -- Gruß Marco Muell und Spam bitte an [email protected]
