But what does the above mean

It can mean that

*  They do no spamfiltering from their users to users outside their network

*   Their mailservers IP addresses are used by others because they use no keys or identification mechanism

*  Their mailservers are being used by others  (maybe the same trick as was used against the mailservers from Vlaanderen.be)


Who knows ? The administrators can and they should start to pay attention because already two servers are in an automated blacklist. This can mean that certain mails from their users won't be accepted without explanation by some mailservers that use these blacklists as such. These mailservers are used by thosuands of businesses and people. Who often don't have a clue.
