You published a DMARC record months ago. Every checker says it's valid. No reports have ever arrived, and at some point you stopped thinking about it and quietly concluded nobody's forging your domain.
You don't know that. You just can't see.
Two causes account for almost all of it, and both leave the DMARC record itself looking perfect.
1. Your reporting address never agreed to receive them
This is in the spec and almost nobody knows about it.
If your rua= address is on a different organisational domain from the domain publishing the record, , a free checker that tests both of these — whether an external rua= is actually authorised, and whether the reporting address can receive mail at all. It's the failure mode I've seen most often and the one fewest tools look for. No signup, and checked domains aren't logged.
If you've had reports silently missing for months, I'd be curious which of the two it turned out to be.
