Gmail has never been a problem for me, even when I only had SPF, sending from my server hosted at Rackspace. But I've had my domain for 20+ years, and Gmail since 2004, so they have had plenty of time to figure out its not a spam source, so this might not have been a fair test.

I just gave Yahoo a try, and that did go to spam, even though it was happy with both SPF and DKIM. I marked it as not spam, and then went and sent another. That went through fine.

I also tried Live. It says my SPF and DKIM are fine, but sends it to the spam box. I marked it as not spam. Nope. Next one still went to spam. Marked that as not spam and tried again. Still spam. Marked that as not spam, but didn't try sending another one yet. I'm going to wait a while, to allow for the possibility that it takes them a while to apply feedback.

I also tried comcast.net. Went through fine.

Can't running your own email server be done through pulling a well-curated library on a daily basis?

Not a library, because a mailserver consists of a lot of moving parts and external configuration (DNS etc).

mailinabox.email is probably close to what you want, though. It's opnionated and my tip is to follow those opinions to the letter (or use another such project).
