you're probably talking about this policy: https://postmaster.t-online.de/index.html#t4.1 That's not really new - and existing mailservers seems to have an automatic good scoring/trust from mailings in the past. That's why very few people, even postmasters, notice this policy. T-online refers to standards and legal regulations, enforcing their policy. In special "RFC 1912, FCrDNS, EU-Richtlinie 2000/31/EG Artikel 5." (cite from link above). Not much fun for those who have to bring up new mail servers, but the manual(!) whitelisting will certainly keep a lot of spam off their servers. (Just got a new customer's mailserver whitelisted today).
