Don't know you did a reboot and before that all log files safed wich update you could see in some log files maybe.

AL dns tests ok?

If your domain is thespam... then Server Apache/2.4.6 and X-Powered-By PHP/7.3.10 the version should not be open known take care of config for that.

Also you have hostname and not mail. saying by dns test
