Add SMIME signature information
It would be great to have an indication/information on a SMIME signature of a message instead of just seeing the "smime.p7s" file attached.

Though this is not the most critical feature, still some instances it would be usuful to see the signing information to validate it.

a full implementation of SMIME could also be a differentiating factor for regulated business (healthcare, finance, aeronautics) sectors to choose Proton Business tiers, so they can also manage and send signed or even encrypted emails to their customers.

in Switzerland more and more government owned entities send SMIME signed emails, especially those entities impacted by phishing, i.e. post.ch
seeing a visual validation of the correct signature for these emails would help users (especially elderly, who are not trained against phishing) to validate the statements in these bulletins. -

Same here. We don't even need a full implementation. Just showing signatures would already be enough for me!
