RFC 7489 & 8460 SMTP Report Monitoring Utilities.

Install

.. code-block:: bash

python3 -m pip install email-report-checker

Note these are for my hobby domain, do not try running them on even moderate traffic MTAs

RFC 7489 Domain-based Message Authentication, Reporting, and Conformance (DMARC)

First ensure your DMARC DNS TXT record contains rua and ruf to request reports:

_dmarc.zi.is.		3600	IN	TXT	"v=DMARC1; p=reject; pct=100; ruf=mailto:[e-mail]; rua=mailto:[e-mail]; adkim=s; aspf=s"

Then load the reports via IMAP:

.. code-block:: bash

dmarc-report-checker m.zi.is [e-mail] Archive > dmarc.json

And report your statistics

.. code-block:: bash

jq '[ .[].record.row | select(.source_ip == "68.183.35.248") | select(.policy_evaluated.dkim == "pass") | .count | tonumber] | add' dmarc.json
jq '[ .[].record.row | select(.source_ip == "68.183.35.248") | select(.policy_evaluated.dkim == "fail") | .count | tonumber] | add' dmarc.json

RFC 8460 SMTP TLS Reporting

First create a DNS TXT record to request reports:

::

_smtp._tls.zi.is.	3600	IN	TXT	"v=TLSRPTv1;rua=mailto:[e-mail]"

Then load the reports via IMAP:

.. code-block:: bash

tls-report-cheker m.zi.is [e-mail] Archive > tls.json

And report your statistics

.. code-block:: bash

jq '[.[] | [.policies[].summary["total-successful-session-count"]] | add] | add' tls.json
jq '[.[] | [.policies[].summary["total-failure-session-count"]] | add] | add' tls.json
