I am sure a senior person from eUKhost will be more than happy to address your concerns. If the people you are getting through to in support are not understanding you properly then it might be a good idea to talk to a more senior person.
Don't forget, I know it must be really really frustrating for you but if you manage to explain exactly what you want and what you don't want I am sure eUKhost can make a note of it on your account so that you are not affected.
The only spam settings that I know that eUKhost update regularly are the global spam settings but this affects all customers on all servers and there doesn't seem to be a global problem so maybe the source of the problem is somewhere else.
As I said I am sure you will get an efficient response of someone senior at eUKhost so you can address your concerns directly to them and they can check everything is working fine on the eUKhost end of things.
