Exim 4.92 has experimental support for DMARC and for ARC, but it's not enabled in Arch Linux. What is the policy for enabling experimental features? Could it be enabled?

For DMARC it would be setting `EXPERIMENTAL_DMARC` [0][1]. The main dependency, Opendmarc, is already packaged for Arch.

`EXPERIMENTAL_ARC` support [2] does not depend on anything and could be enabled right away.

This task depends upon

Would be very nice to have support for DMARC and ARC, if at all possible :) Added my vote

Perhaps DMARC support should be deferred until after  FS#63812  CVE-2019-16378 is resolved.

Unlike similar issues that were open for SPF & DANE that had been resolved but the issues not updated, this one does not appear to be fixed yet.

As of 4.93 upstream DMARC support is considered stable. I think it should be brought downstream to the Arch builds by default.

The CVE issue in opendmarc linked in comments above has also been fixed.

Please provide a diff of the changes you made to the PKGBUILD to enable DMARC.
Have you encountered any issues during your testing of the feature with the modified package?
