What got so complicated? Things like reverse PTR and SPF are trivial. DKIM is a bother to set up but you do it once during an annoyed afternoon and never need to look at it again. DMARC is as easy to set up as DKIM.

> why isn't our mail just routed to a three-word address?

If only there was something that could take words like "grdotcloud gmail com" that we could use to deliver mail!

From my apartment with DSL it wasn't exactly easy. Those TLAs didn't exist twenty years ago.

Yes you do all that plus spamassasin, and then still your outgoing emails don't arrive, and your incoming emails still contain spam.

That's not my experience. MS Outlook seems to have it's off days, but email usually arrives just fine. That's even on Contabo's network, which is listed on that one "your ISP doesn't do enough to stop spam" blacklist Microsoft annoyingly refers to.

I don't see any spam in my inbox either, the little spam I do receive ends up in the spam box where it belongs.

Whatever mail setup Mailcow defaults to has worked great for me. Mailcow and mail-in-a-box have made the classic email setup very painless.
