if you have an A record but no MX, people will just try to connect to
the A record.
Though I've never tried it for domains that lack an MX DNS entry, I do
think overall that DMARC (and SPF) are both good things to configure
for
Use a null mx instead.

Implement DKIM with as many of your third parties as possible. Most have
now realised that they can do their own key-rotation if they simply
specify two CNAME records for you to put into your zone file (rather
than issue you a key, or have you issue them one). Third-party SPF will

1. Yep
2. This is whatever domain was in the Header From (5322.from) of the emails
being described in that row. If any email is sent "from" a subdomain that
doesn't have its own DMARC record (as seen by the receiver), that subdomain
will appear in a line as well.
3. The Aggregate report .xml has
No, mfrom is the RFC5321 sender (the MAIL FROM: during the SMTP
transaction). The user visible from address is the RFC5322 from header.
Which is why even though it passed SPF, SPF Fails on DMARC evaluation
because 5321 mail from domain of "ESP.com" doesn't align with the 5322 from
header domain of

What is a DMARC syntax error? (Which tool gave this? What operation was
it performing at the time?)
Yes,
example.com TXT "v=spf1 -all"
_dmarc.example.com "v=DMARC1; p=reject;"
is a reasonable way to announce that a domain can never be used for
sending email.

There's nothing in the base email protocols that prevents one from sending mail
as you.
