It sounds to me as there would be an easy way of making signing mails much more practically useful (in particular against spam/phishing etc): Would it be very hard to show a visible warning when I read an incoming email that is not signed but coming from a sender that has in the past signed her email? (same/alternative for encrypted)?

The argument for it would be similar to certificate pinning for SSL.

    Hi Robert,

    thank you for this feature request.
    Technically it would certainly be possible by storing a list on disk of addresses which have signed messages before and with the fingerprint of keys they used to sign their messages.
    In practice this would probably result in many false positives, especially if you receive messages from mobile users which often don't use PGP on their mobiles.

    We will create a ticket for this feature request and look into the viability.

    I agree with the mobile device problem (I myself don't have my private keys on my phone). But the whole purpose of signing gets lost when the recipient does not notice a missing signature.

    Currently, there is not even a red thingy that catches my attention when a signature is missing where I should expect one whereas the fact that a message is correctly signs which is displayed has much less practical relevance most of the time. But of course, it's all psychology,
