+| Suped | look up and validate an individual domain's DMARC record, including syntax, policy and reporting settings {[suped_dmarc_checker]} | **alive** — free web-based diagnostic |
 | ''libspf2'' | the C SPF validator embedded in several MTAs; the subject of {[bennett2022_spfail]} | **stalled and this is a finding.** No tag in the repository at all; the last version bump was 1.2.11 on 2021-06-09, and a commit titled //"Fix integer underflow"// landed 2023-10-04 and **has never been released**. Upstream has shipped no release since 2021, so the fix reaches deployments only through whatever distributions have backported it — which is itself an unmeasured question. |
 | OpenDKIM / OpenDMARC | the reference milters | OpenDKIM dormant (last commit 2018-02-25); OpenDMARC last tagged 1.4.2 (2021) with bugfix commits into 2026 |
