Black listed

Hello.
I want to report that   sender1.zohomail.com is been black listed by UCEPROTECT-Level.
If I send emails to some recipients, I get the following email back:

    ----- The following addresses had fatal errors -----   

   [Status: ERROR, Address: <obdsub1@tresnamuda.co.id>, ResponseCode 454, 4.7.1 Service unavailable; Client host [135.84.80.216] blocked using dnsbl-1.uceprotect.net; IP 135.84.80.216 is UCEPROTECT-Level 1 listed.
