Implications unknown! Not quite. The ticket is wrong in mentioning bounces, because they don't trigger an aggregate report. Aggregate reports cover _any_ message that is received with a From: domain having a DMARC record and a rua address. That obviously includes any aggregate reports that is received from the relevant address. The best solution I saw is not to send aggregate reports from a domain that has a DMARC record with a rua address: http://lists.dmarc.org/pipermail/dmarc-discuss/2018-October/004164.html When I read that, I changed the From: header field of my generator, but I'm not sure I did fix anything. Once triggered, that kind of loop would last forever, with <count>1</count> every day from both sides acknowledging each other's report. I looked for such a loop and found none, perhaps because every other domain had already applied the trick?
