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

<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)

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

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

.ru is not blocked. The connect is originating from a .xyz host.
