Your message cannot be delivered because the message is seen by the KPN spam filter as a virus, spam, phishing or has been blocked.
Contacted KPN this is the answer:
Thank you for your message. As far as we can see, you use a VPN connection to send your e-mails. Large amounts of phishing/spam have recently been sent from the connection in question, as a result of which it has been identified as a source of spam by our spam filter supplier.

Do more people have this problem?
