But what I miss in kamil+PGPG is an encrypted
mail-subject, e.g "Subject:
[trinity-users] Re: more re. tde and qt5" beeing replaced by a random
string, which gets replaced on the receiver side with an embedded subject
from within the encrypted mail. Reason is, that a lot of users use a
subject that tells a lot about the mail content, at least enough to let it
be sorted in "interesting" or "junk".
As far as I know the subject is required by the mail server and is not part
of the RFCs I read so far.
Whatever protonmail is - the base concept of encryption is implemented in
kmail+pgpg and there can not be anything else to provide secure
communication that is not part of this implementation.
