S/Mime Support
I would like the ability to import an S/Mime certificate and use to sign/encrypt messages to other users with S/Mime certificates.

This would be amazing! Please support this alongside PGP, ProtonMail :-)

How can protonmail call itself most secure and not have S/MIME support?
-
Mark commented
Yeah, please add this feature. :-)

It would be really handy if I could sign with S/Mime, PGP/Mime is very niche and not widely adopted.

It would be useful for ProtonMail to have S/MIME support to sign messages. Apple Mail does it, Outlook IOS can read S/MIME signed messages and display a verified badge, as Apple does. Any timeline for this?

+3 I have been using S/MIME for over a year now. It is natively available on all my iOS devices by simply importing a .mobileconfig or .pcks profile. Likewise it's supported by Thunderbird on Windows out of the box. It doesn't get easier than that. What remains cumbersome is where or how to get a certificate/profile - same as with PGP.
I looked at PGP in the 90s as well, great to work with privately, but it's not supported natively by most applications. Quite frankly, if it's so difficult to integrate PGP (an add-on of sorts every time?) then it should exactly NOT be recommended for personal use, in my humble opinion.
SMIME is much more ubiquitous. Therefor, please reconsider adding SMIME support. No one is asking that you abandon PGP, but please add SMIME? Many will appreciate it, you may even win new users.

+3 please implement this... I agree PGP works great if the other end is also on ProtonMail, otherwise S/MIME looks practically only way to sign an email as not many have set up PGP already.

While I love PGP, it remains.a niche.

Nowadays, even Gmail — both free and G-suite — supports S/MIME digital signatures in received emails (Gmail doesn't support S/MIME fully-encrypted emails instead, but this is not the point). When the sender uses a valid S/MIME signature, Gmail will say that the sender is verified by a public CA and the email message has not been compromised.
I don't understand why Protonmail refuses to do the same. It doesn't have to support full S/MIME encryption: recognizing valid S/MIME signatures would be great!

I would love to see this feature for message authentication and encryption.

Yes please, this is big. The vast majority of companies that routinely use encryption use S/MIME, not PGP. (Barring maybe newer security-focused companies, but good luck communicating with government using PGP.) Someone recently asked me to send them a document with personal information encrypted using their S/MIME key. When asked if they had a PGP public key, they had no idea what PGP even was. This is the general response I get. At this point, PGP (while great) is mostly still for tech savvy people. Even in 2020 PGP is a PITA to setup for most people not using ProtonMail. ;-)

The ability to read signed emails would already be great . It's really annoying when people send you signed emails and you cannot read the content.

My government issues me with certificates I can use for legal comms in country and with all local, regional, national agencies. Protonmail can only be my secondary email system while I cannot communicate with gov ( not to say many businesses )

I agree with the comments below, this is needed for business communication and would make this a real Outlook/Microsoft alternative.

I also would like this feature. As other people have mentioned, S/MIME is widely used in business (at least in Outlook) for message authentication and encryption. It would be very nice to be able to seamlessly send encrypted messages to those users, even if we had to provide our own S/MIME certs or something.

Would like to use all my votes on this subject. Are even ready to pay an increased fee for this feature.

Yes please !

I'd also like to have this feature implemented. S/MIME is often used in business so it would really help.

S/MIME would be great for replying to users who sign their emails with certificates securely.
