The domain owner can specify what policy the receiving server has to apply if the DMARC check fails.
dmarc=fail (p=NONE sp=NONE) smtp.from=azfamilyflorist.com header.from=moldtechsl.es;
In this case the policy (p=none) is set to do nothing (none). So the server follows the policy and does nothing.

If you want a stricter policy change the DMARC DNS record and replace p=none with p=reject.

More information on DMARC can be found here: What is a DMARC Policy? | P=Reject | P=none
