I don’t get why they call hosting a mail server being your own ISP. It’s a very very loose definition of the term “ISP” there. ISPs may provide mail services on the side, but that’s not what makes them an ISP imo—its providing internet access that makes them an ISP.
Apparently some people consider email providers ISPs in their own right, though? Seems like confusing terminology.

“Once upon a time there were… people who were capable of RTFM and configuring UNIX services without using overly bloated container based solutions that are harder to manage and configure then they should. Around the same time there were also many mail servers on the internet. If your organisation wanted to receive and send emails then you would have your system” > Introduction fixed :)
Now this a very recommended and very great guide.
