Re: [ietf-smtp] ietf-smtp(_at_)ietf(_dot_)org and DMARC with p=quarantin

In article <066CEDBC-8DD0-45B0-BE9E-B06FECD6C93B(_at_)aegee(_dot_)org> you

There are certainly people who believe that, but they are mostly wrong.

You get the same failure reports with p=none as p=reject, so that's
not it.  I have p=none on all my domains and have collected 170,000
aggregate reports and 77,000 failure reports so I speak from
experience here.

What pct=0 might or might not do is to trigger recipient filtering
rules and mailing list rewrite rules, but that is entirely up to the
people who run the lists.  They can and will do whatever they want.
