if the reason why you want to utilize delta chat is the layer of encryption
which delta chat can add, then it is unacceptable if for
any reason delta chat encryption fails, emails get
emailed without the delta chat encryption layer. People to
whom the delta chat encryption layer is paramount, will prefer
that a given email is not emailed, if the delta chat encryption
layer failed.
Therefore in settings → autocrypt a forced encryption
option shall be added, such that if the delta chat encryption layer
fails an email will not be emailed. Thank you.
