Doesn’t Posteo have the same price?

Stalward’s website looks vibe-coded.

I personally self-host my mailbox and relay outgoing mail using Emailit.com (Czech). I have all possible addresses in my domain, and can put whatever filters I like. However, I appreciate Posteo very much, I would have used their service if not for the desire to use another domain.

Besides the OP’s point, it also disallows standard protocols.

Is its bootloader unlockable, or locked to Graphene? Graphene seems to be trading freedom for ‘security’.

Refuse it, ask for a chip card-based solution, which is very feasible. EU will require banks not to ask for smartphones with the PSR.
