I’d recommend looking again, as I think that advice is becoming dated. Greylist and DKIM make spam prevention super simple, ironically because the centralization of email towards Outlook and gmail has trained pretty much every sender to follow the rules or your email doesn’t go through. And then Greylist catches the rest, because spammers don’t come back and retry after a few minutes.
Comment on What external services do you use for your selfhosting setup?

An external email host. Life is too short to deal with frustrating email issues.

The problem isn’t incoming spam, but rather not being able to send to the larger email providers because of arbitrary spamfiltering on their side.

True. I kinda dodged that problem by having a personal .net domain that’s older than wikipedia.org. My understanding is that you can raise your domain’s reputation with some work.
Honestly the most important thing I use my domain for is easy-to-delete mailboxes and aliases to give to companies and contacts. That’s just incoming email.
For outgoing, there are services that let you send them an email and receive a report on any mistakes or misconfgurations they notice. I followed the first tutorial I found that didn’t seem like it was just advertising “see how hard email is? Looks impossible doesn’t it? Why not pay us instead.” Ended up being at linuxbabe dot com, run by Guoan Xiao, with part one titled “Build Your Own Email Server on Ubuntu: Basic Postfix Setup”. No links but search engines find it.
Big difference is I use OpenLDAP/slapd, and I put different components on different VMs. Took maybe a couple weeks of free time here and there, but I’m proud to say my outgoing emails seem to be accepted everywhere. Not that I send many, really.
Eventually planning on implementing filtering for terms and conditions updates for long-forgotten sign ups. I would like those to bounce.

Same :( admittedly I never tried, but it’s the one thing everyone recommends against.

It is a real pain, I host a small email service, and spend at least an hour a day dealing with issues sending emails.Mainly because users think it is entirely acceptable to send thousands of emails a day thinking they will get results from it. However, I have to say that I am telling most people to move away from email as it isn’t that secure and those free email addresses from old ISPs are terribly insecure. Also seeing a lot of data stolen as people think 2FA via email is great, so hackers just hack the email server and boom
