That was exactly it. Is it legal in Germany for a network to ignore abuse notices unless they come from Gmail?
Unless you are whitelisted by T-Online/Telekom. Contact them and they will whitelist you.

How would I do that apart from emailing them?
Try their postmaster address. If you get a bounce, it should include another address that does not require whitelisting. IIRC it was something like postmaster@rx.t-online.de -- Gruß Marco Muell und Spam bitte an abfalleimer2002@stinkedores.dorfdsl.de
