A question about practice rather than policy.
I've been looking at how small and mid-size senders configure email
auth. The common landing spot is DMARC p=none with rua set,
sometimes for years. I understand why people start there, but I'm
curious what actually moves a sender off it.
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?
I receive rua (and sometimes ruf) reports whenever I post to
any of several lists. Since I'm the only user of this domain
and wish my worlds of wisdom to be seen, I don't expect to change
my DMARC policy as lng as the lists that interest me break DMARC.
