About Kevin's email [1] …

I was hesitant to talk about the problem I had in replying, because it's well
known that the Big Players (Google and Microsoft in particular) don't really
care about smaller email servers, making it difficult to self-host email.

Yet … the bounce message I recieved contained the following:

-----[ data ]-----
Diagnostic-Code: X-Postfix; host
   hotmail-com.olc.protection.outlook.com[104.47.66.33] said: 550 5.7.1

That link? Absolutely useless. To address the issue, I would have to sign in
to my “Microsoft Account” or pay for services like this company [2] that
“ensures” email delivery (which I'm reading as “pay to play”). And of course
I'm a company, because who would be so silly as to run their own email
server? Sheesh!

Why Microsoft couldn't just send a link to their Office 365 Anti-Spam IP
Delist Portal [3] in the first place (which took entirely too long to find
and didn't appear on the link they did send), I don't know—I guess that could
make it too easy to “game” or something.

Mainly, I'm writing this for my future self to save some time when this
happens again.

Update about an hour later …

The bounce came from outlook.com, but Kevin's email address is from
hotmail.com, and it's hotmail.com that has a block on my IP (Internet
Protocol), not outlook.com.

I found that out because I followed the instructions on the “Office 365 Anti-
Spam Delist Portal” and it said “Oh! You aren't blocked! Try this link!” with
“this link” asking me to log into my “Microsoft Account.”

Seriously, Microsoft? XXXX you.
