You can have them encrypt your mail with your public key as soon as it arrives, so that your mailbox is always encrypted.

I like the idea, but can't they read the mail on arrival and before encryption anyway?

Yes, but this is true of all standard email services. If you want end-to-end encryption then you need to have your correspondent encrypt their message with your public key before sending, as with any E2EE email.

The purpose of encrypting incoming mail is for mail that arrives unencrypted (most mail) so it does not sit in plaintext on their servers.

They can read them, obviously, but this way they are stored in an encrypted format in case of breaches or warrants.

Yes and no.

AFAIK, warrants in Germany can be issued to monitory communications traffic, so they'd have to copy any new mail in plain for the authorities. But yes, old mail would be secure.
