What it does
mailbox offers paid email hosting alongside calendar, drive, office and meeting features. Its security documentation explains transport, storage and OpenPGP-related protections.
The Light, Standard and Premium plans separate a basic inbox and calendar from custom-domain, office and shared-storage needs. The official table also distinguishes mailbox-address aliases from custom-domain aliases.
For account access, mailbox documents two-factor authentication and separate email-app passwords that can be created and blocked individually. Its security page also describes PGP and S/MIME for protected correspondence. Those message-encryption routes answer a different question from controlling which mail client may sign in. The service offers a trial for evaluating an existing client and domain setup.
