Looking at this
I noticed that over 90% of the lines spat out were for rspamd. Thinking about it, the way my network is set up and how my mail works, there’s no reason for me to be running rspamd in ns8, so I thought I’d disable it. But that doesn’t seem a simple task. After turning off AntiSpam in the Filter settings, I get this:
Is there any way to completely shut down rspamd.
Cheers.
I tried disabling the service but it seems to break mailing completely.
runagent -m mail1 systemctl --user disable rspamd --now
But it’s about prometheus scrape timeouts, I don’t think that the rspamd timeouts are related to your issue.
No, I don’t think they are either, I’m still researching that. It was just seeing so many timeout messages related to rspamd that made me think about why/if I need to be running it.
Guess I won’t try that then. 
Cheers.
