Hello @nasim.nazanin88 – if you and friends use national iranian e-mail servers with Delta Chat, then your messages will become end-to-end encrypted between you. If you also use it to e-mail non-delta chat users then those communications will not be encrypted, usually.

For DC users to protect messages against potentially hostile e-mail servers it’s best to use QR codes for setting up contact with each other, and then create so called “verified groups”.
