As of today 31 Jan 2021 nearly all incoming mail is getting rejected because the sending mail servers are in an RBL.
And adding to the disable/enable file /etc/csf/csf.rblconf ( example) disablerbl:dnsbl-3.uceprotect.net isn't working either.
Any suggestions? Is there a RBL that's missconfigured?

Solved!
It seems that spamcop.net FORGOT to renew their domain name! https://forums.cpanel.net/threads/spamc ... ed.685309/
Disabling their RBL in Exim until they renew their domain will fix it.
