Ok, strange one this one getting milter-reject: 4.7.1 service unavailable - try again later in the mail logs. this has been going on for a few days now. checked dkim and even changed the permissions to 640 (another post mentioned it) disabled spam checking in the gui, disabled antivirus checks and still no email is coming into the system.
i did have crowdsec installed which i have now uninstalled just in case but mail flow is still not happening.
also it looks like no email has appeared in the rspamd gui for about 3 months
Are the mail containers running? You could also check the mail app status page.
[root@ns8rockytest ~]# runagent -m mail1 podman ps
