Seems de dmx.net / dmx.de SPF is broken:

> set type=TXT
> gmx.net
Server:         10.10.21.4
Address:        10.10.21.4#53
Non-authoritative answer:
gmx.net text = "v=spf1 ip4:213.165.64.0/23 -all"
Authoritative answers can be found from:
> gmx.de
Server:         10.10.21.4
Address:        10.10.21.4#53
Non-authoritative answer:
gmx.de  text = "v=spf1 ip4:213.165.64.0/23 -all"
Authoritative answers can be found from:

this does not include: 
Received: from pD9E05917.dip.t-dialin.net (EHLO [223.1.1.128])
> [217.224.89.23]

The managers of the dmx.de / dmx.net should strip that header to make their SPF 
record ok, or include their dial-up users IP addresses.

Huh?? 223.1.1.12? Is 213.165.64.20 part of your trusted networks?
Actually the doc for the SPF module says "trusted_networks" but
shouldn't it be checking "internal_networks" instead?

Anyway, it fails because it's checking the wrong IP because it thinks
you received it at one stage earlier that you did. That's likely because
either or both of trusted_networks and internal_networks are not
correctly set.

HTH,
Bret
