Hi,
Thanks, I read about that now. The problem is in my ISP. They do not support 2048 bit key at this moment. :-( I'm disappointed.
Best Regards.

This isn't really an exim issue, but a DNS one.
The DKIM DNS TXT record for a 2048-bit key is more than 255 characters so
you need to be extra careful how you enter it into the DNS database.
https://www.experts-exchange.com/questions/28381437/Is-there-a-registrar-that-will-allow-2048-bit-DomainKeys-DKIM-values-in-a-domain-TXT-record.html
suggests splitting the key into multiple entries, and discusses how
to do this for at least one DNS server.
