Re: [Evolution] Evolution 3.18.5.2 Encryption with GPG from Hotmail Account message structure

Hello Milan

I see you added a workaround for reading such broken messages, however I
think it'd be more important to avoid sending such bad messages [when
using evolution-ews].
I have opened Bug 785840 for this.


As the requisite appears to be that there must a plain text part, I
suggest sending:

 multipart/alternative
   text/plain
   multipart/encrypted; protocol="application/pgp-encrypted"
      application/pgp-encrypted
      application/octet-stream; name="encrypted.asc"


With the text/plain part being a dconf-customizable text like 
«This is a PGP encrypted message but your mail user agent does not
support reading PGP/MIME emails. Please ask the provider of your email
client to support PGP/MIME (RFC3156) for an optimal experience.
As a workaround, in case your email client does allow you to download
the file named encrypted.asc, you may be able to decrypt it using an
external program.»


(Yes, it's overly long, but some people need a decent amount of
hand-holding for being able to deal with PGP messages, eg. they expect
that an encrypted email should appear as an attachment)


Best regards
