Does Tuta do that? I've missed that discussion in that case, I've been using them myself and if I can expect to be locked if I want to try another provider I'd rather switch now than when it becomes an even larger hassle

Perhaps they've changed, but last I checked they didn't allow IMAP/POP3 due to "security concerns".

From their howto site:

Can I use a third-party email app like Thunderbird? No, this is not possible for security reasons. Tuta does not support the use of third-party email clients or the protocols IMAP/POP3/SMTP as we cannot guarantee end-to-end encryption of your data. Instead, Tuta offers email desktop clients for Linux, macOS and Windows as well as a web client and apps for Android and iOS. We aim to provide all required functionalities with our own apps, for instance, offline access to your encrypted data is possible with our apps.

my required functionality is the ability to integrate other services like paperless etc.. In my support requests to them they made it very clear that they don't aim to provide that.
