I just set up a new email account, pine64.org rejects my emails as spam

I set up my own email server at koszkonutek-tmp.pl.eu.org. I wanted to use it for some time until I obtain some other domain I wish to stick with. I did set up dmarc, DKIM and SPF properly. After I started writing email to Gmail useds, Google started sending me reports like this one which seem to confirm that I indeed did it all correctly.

My email to users of Protonmail and Gmail lands in spam nevertheless. I though it might be because they haven't "learned" my domain yet. This did not bother me much since it is just a matter of having the person I correspond with mark some messages from me as "not spam" and then subsequent ones start to appear in INBOX. Unfortunetely, when I attempted to write to pine64's support, I got a "mail returned to sender" message informing me that my mail was blocked by some spam prevention mechanism. What's going on here?

There seem to be some third parties that maintain white-lists of legitimate email servers but registering with them seemed to be too obscure of an action for me to consider reasonable. What do you think? Do you have any advice?

I have read somewhere that if your are using your personal IP to operate your email server, it could get classified as dynamic (whether it be, in fact, dynamic or static), and in turn incoming emails sent from your server blocked as potential spam.

Also, concatenating top-level domain labels is not recommended. It is often used by malevolent actors to mislead users to non-legit websites, so spam filtering rules might also flag it. For instance, if goldbank.ch was a bank's website, then scammers might send phishing attempts from customer-service[at]goldbank.info.ch and try to get their targets to visit goldbank.info.ch, which to many unsuspecting users might sound legit.

I would set up a free protonmail account for contacting people like that. There's probably not going to be any way to please every one of these spam filters when you are trying to run your own email server, so at some point you may have to have a backup free email like protonmail or tutanota in order to break through and actually communicate.

That's just my totally uneducated opinion. I know next to nothing about setting up and running email servers, so not trying to put that forward as any type of expertise.

UPDATE: I tried writing to them from another email account and I got this autoreply:

Obviously, that ticket site doesn't work without javascript and its javascript seems nonfree (from quickly looking at page's source in the browser).

What's ridiculous, is that this autoreply itself failed its domain authentication test...

Pine just lost even more in my eyes :c

Well, thank you for your replies, at least. It seems those anti-spam measures harm decentralization of the internet :/

My thoughts exactly. Or more precisely, that deceptive actors can easily harm the potential for federation.

You mentioned that you are planning to use a different domain name at some point. If hosting is an option for you, you could also set up and manage your email server on a remote machine and benefit from the default whitelisting of your hosting service provider (although they might favor their own email services for similar reasons).

I started reading "GANDI'S GENERAL TERMS AND CONDITIONS OF SERVICE" but then recalled Hyperbola moved away from them out of privacy concerns. That's the problem - it is easy to purchase hosting and a domain if you have no principles but at the same time it's challenging to find a provider who's actually ethical and doesn't require nonfree js.

So whoever I choose, I must make sure they allow access to port 25. I'll remember
