I recently got 11 messages from “system” on my forum indicating a single message had been auto-flagged for spam. It was the top message in this thread: Fedora webserver https setup - Let’s Encrypt Community Support.
I also got 10 messages from “system” about another auto-flagged message, /root/.local/share/letsencrypt/bin/pip: No such file or directory - Server - Let’s Encrypt Community Support.
Neither of these was actually spam, but that’s not a big deal. I’ve adjusted the spam host threshold. However, it’s weird that I got so many duplicate messages about it.
