Detailed explanation-1: -An IdenTrust Secure Email (S/MIME) certificate is issued to your confirmed email address and is used to sign and encrypt email communications. A digitally signed email provides assurance to the recipient that the email originated from your verified email address and that it has not been originated by an attacker.
Detailed explanation-2: -S/MIME improves email security by encrypting messages and adding a digital signature. Using S/MIME helps protect your users from phishing, harmful software, and other email threats. S/MIME requires that both the sender and recipient have it enabled.
Detailed explanation-3: -An S/MIME certificate needs to be installed on the email clients of both the recipient and the sender to ensure email encryption at both ends. When an email is sent, the sender encrypts the email using the recipient’s public key and the recipient decrypts the email using the private key.
Detailed explanation-4: -Open the Settings app. Choose Mail > Accounts. Select the account that has messages that you want to encrypt by default. Choose Account > Advanced > Encrypt by Default, then turn on Encrypt by Default. 17-Jun-2022
