Suggestion: Generate DMARC authorization

When a DMARC DNS record is created in a zone, and the MX domain is hosted locally, create a DMARC record in the mail server domain.
Example: Hostname = foo.tld, MX mailserver hostmame = mail.bar.com

When we create this in zone foo.tld:

_dmarc.foo.tld. TXT
      v=DMARC1; p=reject;
      rua=mailto:postmaster@bar.com;
      ruf=mailto:postmaster@bar.com;
      fo=0:1:d:s

Generate this in zone bar.com:

foo.tld._report._dmarc.bar.com. TXT v=DMARC1;

It must be verified that bar.com is a locally defined zone, and that the mailto value (postmaster@bar.com) is an active address.
