cloud black list

[UnitIT 0]

Hi,

A customer of ours are having problems with receiving certain mail since a couple of days. The reason ESET provided is: IP(x.x.x.x) foud on cloud black list 1. 

The IP it is not on any major blacklist. It's also not blocked at the server side. 

Can someone tell me what cloud black list 1 is? And how to delist the IP

Thanks in advance
