I'm not sure whether I understand your
requirements. An email with a
link to the portal page is always an email with an encrypted PDF (when
OTP mode is used). The user has to login to the portal to retrieve the
password for the PDF, hence the link to the portal.
well the recipient gets an email with the attached pdf.
It is encrypted with the static password, assigned in the user profile.
When I remove the password and OTP is activated, the messages will not be encrypted.
