Scott took the time to define PSDs and PSOs in RFC 9091, restated in
Sections 3.2.8 and 3.2.9 of the current draft. Since the definitions of
Organizational Domain (both the current 3.2.7 an my proposed change)
require PSD + 1, a PSD has to be a proper subdomain of another PSD in
order to admin an Organizational Domain itself.
I don't agree, but whatever.
PSD + 1 != PSD, since 1 != 0. No need to agree or disagree...
_dmarc.ac.me TXT "v=DMARC1; p=quarantine; adkim=r; aspf=r; fo=0; pct=100;
rua=mailto:[email protected]";
ac.me mail is handled by 10 mail.ac.me.
ac.me TXT "v=spf1 mx ip4:89.188.43.10 ip6:2a02:4280:0:200:89:188:43:10 -all"
All of the above admit no org domain.
If I have a message from [email protected] and it has valid SPF of mail.ac.me, is
that aligned? Why or why not?
I think for a PSD that sends mail, the current definitions would require Mail
From for SPF or d= for DKIM to be the same because they wouldn't end up having
the same org domain. It might be simple enough to say to ignore psd=y or a
lower level psd=n if the 5322.From has a domain with psd=y (they can always
set strict alignment if they don't want lower level stuff to match).
+1
OTOH, if the From: domain is without psd=y, then any identifier having psd=y
cannot be aligned.
