Gnax IP Address Range On Dnsbl-3

Some of our client emails are being blocked and it appears that the whole GNAX range of more than 103680 IP addresses was blocked.

As you should know now: It is not you, it is your complete provider which got UCEPROTECT-Level 3 listed.

Your IP xxx.xxx.xxx.xxx was NOT part of a spamrun, but you are the one that has freely chosen your provider.

By tolerating or ignoring that your provider doesn't care about spammers you are indirectly also supporting the global spam with your money.
Seen from this point of view, you really shouldn't wonder about the consequences.

What I want to know is how often do it happens that a datacenter have all it's IP addresses being blocked?

I contacted Gnax about this but their response was merely that they will take steps and the whole range will eventually be delisted. (Obviously the immediate removal fee of $200 something is too much for them)

Ironically merely a few hours AFTER I contacted them I got a "warning" about spam send from one of our clients.

The date of the email was a few weeks AGO and We already long ago warned our LEGIMATE client that such emails are not allowed and the account will be terminated if it happens again. (In other words WE immediately acted against potential spam while Gnax not and then have the nerve to warn US after WE informed them of the blacklisting)

On the one hand I understand that it can be difficult for a very large provider and uceprotect.net seems a bit harse to block ALL IP addresses due to 0.238 % spam ip addresses.
