How to delete spamy / hidden pages in WordPress and backlinks

I am working on a website and last month we had some viruses that made 1k spammy pages or hidden pages.

My question is how can we delete those pages.

I want to tell you that Moz/Ahrefs/SEMRush found those pages but when I click the link it goes 404.

What does CBL mean? How to spot infection by making outbound TCP connections to 110?

I have an IP blocked by Spamhaus CBL, and it tells me the following instruction:

This IP address was detected and listed 2 times in the past 28 days,
and 2 times in the past 24 hours. The most recent detection was at Mon
May 25 02:25:00 2020 UTC +/- 5 minutes

This IP address is attempting to break into POP servers, probably with
stolen credentials, with the intent of stealing email. These are
usually part of targetted phishing attacks.

POP server attacks are usually on port 110 or port 995. This listing
event was for an attack on port 110. You should be able to spot the
infection by making outbound TCP connections to 110 via such tools as
iptables, netstat or ss.

As a reasonably intelligent dumb windows user, how can I test this to see if I do actually have any kind of infection? I know how to use telnet.exe but I have never even heard of iptables, netstat or ss – they sound like linux geek tools to me.

Debian 10.4 / Exim 4.92 add incremental delay to the unsuccessful login attempt answer

Browsed over all the internet, but cannot find an answer – is there any acl or something that I could apply to unsuccessful login attempt to add delay to it? As probably anyone running mx, I have a lot of bots logins trying to guess users passwords. To make dictionary attacks at least a bit more difficult, I’d like to add some (incremental is better) delay after each unsuccessful login attempt’s answer.
But cannot find how to do that with standard debian exim installation. Please share one with a brief explanation. Thank you.
