Hi everybody,the requirement for having an imprint in advertising mails is not limited to T-Online. It’s a legal requirement and also criteria for the Certified Senders Alliance (CSA) which is at least relevant in Germany. For those not having heard of it – it’s a whitelisting project originally from Germany, but going more and more international. In Germany pretty much every ISP and ESP are participating and therefore sticking to the rules.
If I understand well, this is a whitelist, so mail admins can choose to use that whitelist to trust senders, but have no obligation whatsoever to _only_ accept senders on that whitelist. And, in the case of T-online, they seem to only accept senders on that list, which is a very poor idea at best. But, maybe they want to stop their mail business.
