Also Proton since I use the VPN / Domain service. The issues with Proton for me mostly boil down to their marketing and pricing. The bad things to do with logging were something they were ordered to do by their local jurisdiction (unavoidable) so I just consider it as them acting on good faith.
Posteo is almost perfect. It's cheap, can be bought anonymously, runs on other email clients, but they lack a DMARC policy. They don't log IP addresses at all but your mailbox can be intercepted if they receive an order to.
