No match was found for ' ' . Reverse DNS must have a matching forward entry that points to one of your IPs.
How do I create a "matching forward entry that points to one of my IPs" in simple yet detailed steps?

I have already seen both

"DNS Set-Up Checklist - When setting up any domain name on your Linode, make sure you perform the following steps:
1.) Register (purchase) a domain name, if you haven’t already.
2.) Set your domain name to use Linode’s name servers. You’ll need to do this on your domain registrar’s website and then wait up to 24 hours for the change to take effect."
I need to use ns1.box.example.com for my name servers.
This page says, "You can host your DNS information on name servers in one of several locations:
Linode (recommended)
Your registrar
Your own DNS server
Third-party DNS hosting"
but it doesn't show how to not use ns1.custom-name-server.com
Per Mail in a Box, "Your box's reverse DNS is currently liXXX-XXX.members.linode.com (IPv4) and Not Set, but it should be box.example.com. Your ISP or cloud provider will have instructions on setting up reverse DNS for your box."
Mail in a Box says I need to use
ns1.mail.mydomain.com
ns2.mail.mydomain.com
ns3.mail.mydomain.com
ns4.mail.mydomain.com
at my registrar, Google Domains.

Setting up a simple email server is very confusing.
Note that it says "If you are using an external DNS provider, e.g. if you already have a website on your domain name, you may skip this section."
If you're going to use Linode's DNS service, then don't do the nameserver bits - it's going to make this more complicated for you. If you're not going to use Linode's DNS service, then you don't need to setup anything in the Linode DNS Manager. You'd handle all the DNS records in Google's control panel.
Also, per Mail in a Box:
Your box's reverse DNS is currently liXXX-XXX.members.linode.com (IPv4) and Not Set, but it should be box.example.com. Your ISP or cloud provider will have instructions on setting up reverse DNS for your box."

Google says that I have to work with Linode for the Reverse DNS.

Once you have created an A or AAAA record for your Linode's IP in the Google Domains control panel (and once that change has reached the rest of the internet) you'll be able to set Reverse DNS in the Linode's Dashboard under the Remote Access tab.
64 bytes from box.example.com (My Linode IP address): icmp_seq=4 ttl=64 time=0.055 ms
However, when I enter box.example.com into Linodes » linode1234567 » Remote Access » Reverse DNS, I get the following error, • No match was found for 'box.example.com'. Reverse DNS must have a matching forward entry that points to one of your IPs.
So the problem is not the "lack of a matching forward entry". The problem is waiting for the update?

If pinging the real domain gives you the IP, then yes. It's just a matter of waiting for the change to fully take. You should be able to set RDNS in a short while, based on what you're saying.
I have this record:
box A 30m "LinodeIPaddress"
Is there any way to speed up the update?

Done! Many thanks
