Yeah, I run my own email server and have the same issues with the same services as the person who wrote the piece this links to.
In my case users are sending estimates and invoices and monthly statements to their clients and while fake invoices may be a spammer thing those clients know who's sending them an invoice, and why and what for, so an 'Unsubscribe" link would be completely out of context because they are not subscribed to any email list.
I've had the same domain name for over 20 years now and none of my users have ever used my apps to send spam. And as spam and email volume go my server isn't even close to sending out a lot of email.
When I set up a new email server last year, with a new IP address, I had to go through the process of getting white listed. All the big email service providers have ways to do that. Google made it very easy. They gave you a unique string to add it to your DNS records and that's it. Microsoft is so convoluted I've still not gotten anywhere with them. Comcast and others had a few hoops and ladders but nothing that got me stuck.
Personally, while it's a bit of a PITA to setup and manage an email server, it's been worth it.
I used "Mail-in-a-Box". It's pretty easy to set one up with that. It has a built-in DNS server and that's a really great thing to have for managing several domain names and as many email addresses as you want. I've setup email accounts for family and friends as well as throwaways for my wife, who signs up for everything she sees on the internet.
I can move the IP address of my email server to the top of the list in my Mac's System Preferences for DNS and start testing new domain names and changes to the DNS immediately. I don't have to wait for those to propagate to whatever my access provider is using.
So I have 3 servers. An Email/DNS server, a database server, and a website/webapp server running on DigitalOcean's "Droplets". It's a bit of work for a small shop but it's much easier to manage once it's setup and I don't have to worry about any 3rd party service selling out or going under or changing their API to something entirely different. All of which has happened to me in the past.
