[Hidden-tech] Outlook Error Message

[Larry Kuttner]

It is probably the lack of a DMARC record that is causing it.  In that past
year, I have seen several providers start blocking email from domains that
do not have a DMARC policy.
I also recently found that the DMARC policy must specifically have a
quarantine or reject policy.  When I added a quarantine policy to our
existing DMARC, many email recipients that were getting rejected are now
being accepted.

Here's some helpful info:
