SEHL MailSovereign webmail

Your mail, on your own server.

A full mail client that talks JMAP straight to your engine. No third party in the middle, no tracking pixel that you did not ask for.

Remote images blocked until you say otherwise, and message HTML runs in a sealed frame.
SPF, DKIM and DMARC shown per message, straight from the engine's own verdict.
Everything by keyboard — and undo on send, archive, delete and move.
Nothing is invented. If the engine cannot answer, it says so and stays empty.
