It woud be nice if you could implement in addition to PGP s/mime support.
s/mime for encrypted messages and s/mime for digital signature
+1 from me. I would really appreciate that feature too.
Damnit, It's not easy to find some documentation to install plugins into Rainloop. I would have loved to work on this one.

I also would very much like to see S/MIME encryption support.
Indeed - as programs such as Thunderbird's Enigmail get more popular, we receive more encrypted mails in html format or with attachments.
To be able to at leas read these is a quantum leap in usability.
