An email will be S/MIME encrypted to all recipients for which there is a
valid S/MIME certificate. For recipients for which there are no valid
S/MIME certificate, PDF will be used or depending on the encrypt mode,
if PDF encryption is not enabled, the email will be sent unencrypted or
bounced back to sender.

The reply link will be available for PDF encryption so there has to be
an email sent at least once. There is currently no option to initiate a
reply by a recipient without receiving a PDF first. The reply link in
the PDF is secured using cryptographic algorithms (HMAC) to make sure
that a reply link cannot be "spoofed"

If you want to receive S/MIME encrypted email and you want to have the
gateway decrypt the email, then incoming email should be handled by the
gateway first and therefore a receive connector is required as well.

It depends on how you define end-to-end. With a gateway the end point is
the gateway. So for example these two options can be considered end-to-end.

Gateway <-> Internet <-> Outlook
Gateway <-> Internet <-> Gateway

However some would argue that a gateway is not real end-to-end since it
handles encryption for multiple users.

Kind regards,
