Description o 2021-08-02 11:49:29 UTC
Description of problem:

DMARC DKIM domain checks always fail with the following log:

    failure to store dkim (example.com) for DMARC: Attempt to store an illegal value

The reason is the following upstream bug: https://bugs.exim.org/show_bug.cgi?id=2728

For some reason the package still builds, despite the broken signature of this function. Why that is would be another important question to ask. In any case, exim ends up passing the empty string u"" instead of the dkim_result, at the position where the library expects it.

Fedora includes the following patch, which centos is missing: https://src.fedoraproject.org/rpms/exim/blob/rawhide/f/exim-4.94.2-opendmarc-1.4-build-fix.patch

Probably the easiest is to include that patch.

Version-Release number of selected component (if applicable):

Probably all versions epel 7 and 8, which are built against opendmarc 1.4.
