Yep. Its a lot of TLDs that is banned at me, but I haven’t had any problems with .ru so .ru isn’t yet banned.

 

Here is my TLD banlist:

 

  deny

    message = 5.7.1 Banned TLD where sending IP is not listed on DNSWL ( https://www.dnswl.org/selfservice/?action=register )

    condition = ${if eq {$acl_m4}{dnswl_whitelisted}{no}{yes}}

    sender_domains = ^(?i).*\\.(accountant|accountants|asia|auto|berlin|bid|buzz|camera|car|cam|cars|christmas|click|club|college|computer|country|cricket|date|design|download|exposed|email|fail|faith|fit|fun|gdn|global

This crap that ICANN started with “custom” TLDs is of more harm than useful. So much spam TLDs in the registry.

The ".top" TLD is popular among Russian spammers, ".ru" is a little too obvious and honest for what it is, unless that's part of Biden's sanctions, the others you mention look like vice domains, but looking at GitHub:

* https://github.com/dovecot

There's an "Oy" which is a Finnish "osalliyhdistys" and a ".fi" -- I have not heard of recent hostility between Finland and Russia, notwithstanding the Ukraine situation. Your mail client is all configured in Swedish, but Sweden & Finland are not officially part of NATO, AFAIK, and Sweden has its own currency whereas Finland did give up the markka in exchange for the Euro some 20-odd years ago I don't recall.

Thats a TLD ban. Meaning *.ru is banned.

same applies for my domain for example, I ban *.xyz, *.date and a few others.

    Problem is, I need to unpack each of them to be sure, that these 
 are false positives and I'm afraid, that it could lower reputation of 
 my mail server IP address with major providers (like Google Mail).


How can you get a lower reputation? Afaik dmarc is just signing your outgoing messages.

  Marc, my domain already has problems sending mail to you, for example:

<Marc at f1-outsourcing.eu <mailto:Marc at f1-outsourcing.eu> >: host spam1.roosit.eu[212.26.193.45] said: 553 5.3.0
     550We have blocked this toplevel because of spam. Use another toplevel
     until the maintainer has resolved these issues (in reply to MAIL FROM
     command)
