This isn't really an exim issue. As explained in the error message, the
recipient system has decided that they won't accept mail from boxes
where a DNS lookup of the sending IP address fails.
In your case:-
% host mail.ku-gbr.de
mail.ku-gbr.de has address 62.67.222.139
% host 62.67.222.139
Host 139.222.67.62.in-addr.arpa not found: 3(NXDOMAIN)
You need to fix your reverse DNS delegation and zones before that site
will accept mail from you.
