My OpenDMARC broke and how I fixed it

My OpenDMARC package recently broke following an update. Investigating what had happened, it appears that version 1.4.0 has introduced a new feature i.e. support for ARC.

This has required a few changes both in packaging and runtime environment. I am using archlinuxARM and their packaging of OpenDMARC is taken directly from upstream Archlinux. Unfortunately, the packagers missed the requirement that OpenDMARC-1.4.0 needs perl-json.

The added support for ARC also requires additions to the Report Database schema in the form of some new tables and extra fields on existing ones. The History file format has also changed and requires some manual intervention.

In summary, after an update of OpenDMARC to 1.4.0 you need to do the following:

For Archlinux package opendmarc-1.4.0-1, also install perl-json
Update your Report Database with e.g. schema.mysql (recreating the database is the easiest method)
Truncate your existing history file before the next scheduled report import time

I have raised a bug report against Archlinux for opendmarc-1.4.0-1 missing the perl-json dependency so later versions of this package should fix this.
