I am starting to get a nightly status email from mailinabox saying OPENDMARC is not running, and I have no idea why it’s crashing/stops running. I tried looking in mail.log but that doesn’t seem like the right place to look for that error (I can see the “connect to Milter service refused” lines…)
I’ve seen elsewhere that maybe the box is running out of RAM? But I’m only around 40-50% usage average…
