in plesk i see this screen

 

[IgorG]

But this hostname is really not resolvable:

$ host euk15306.eukhost.com
Host euk15306.eukhost.com not found: 3(NXDOMAIN)

 

[SpirosA]

how i can solve this problem?

IgorG is correct it does not exist.

Your also backscattering!

This means spam being sent to you that can't be delivered on your side is being bounced back. As the sender is generally forged on spam your sending out undeliverable messages to innocent people - this is backscatter.

Yo may end up getting on RBL lists due to this, never bounce spam!
