Jens,

Ah, now I understand the underlying issue.

The issue was the failure of reverse DNS for your IP:

  $ host 165.225.72.121
  Host 121.72.225.165.in-addr.arpa. not found: 3(NXDOMAIN)

Null rDNS results are often associated with malicious activity, but not 
always.

Your IP is now unblocked and should be specifically excluded from future 
block lists.
