GMX's conclusion—namely to warn against using blacklists—is pretty stupid. The correct approach would simply be to close the hole, and then there would be no problems with blacklists. And ORDB isn't really problematic—you can start your own test anew and if it goes well, you get removed from the lists. And for anything more complex, there's a contact form.
In any case, there was a concrete reason why GMX ended up in this situation—using sender addresses as the sole qualification criterion for permissions is nonsense, since they can be forged arbitrarily.

Ridiculous. The competition is said to be suspended - where exactly is the serious competition if you come with fake bids? The doubts about such a last-minute offer are entirely justified - either they're paying extra, then it's not a legitimate bid, but price dumping. Or they're making money from it - why was the other bid so much higher then? If you can suddenly save 7 million in a bid without it causing major pain, then something is definitely wrong, one way or another.

Wow, Merkel really doesn't get it anymore, does she?

The reference to God in the Basic Law and in the oath formulas for civil servants is already absurd - what about a civil servant who doesn't believe in God? God won't help him, so what's the point of having "so help me God" in the formula? But to demand that for the EU as well - completely ridiculous. Europe should enshrine its Christian ties, but without disadvantaging other religions in any way - how is that supposed to work? Even now, other religious communities are disadvantaged, or does any religion besides Catholics and Protestants have state-backed tax collection? The state should stay out of the religion issue, period. By the way, there's a nice collection of links around the topic of political atheism at gottloses Ketzer. I found the original article at MEHRZWECKBEUTEL.
