I understand that one way to encrypt Outbound emails is by using the S/MIME protocol to send encrypted email messages. We need to configure a keystore file. This is not a viable solution for us as we will need to collect private-key/public-key from each of the email recipients which means each of the recipient should have a certificate.
Is there any other way to implement email encryption in Pega? Can we use the standard "SendEmailNotification" activity directly with the parameter "EncryptMessage" set to true?
