Email gateway to Sophos UTM

Hello,

I have a question about the email encryption on the UTM. The other side uses an email gateway and encrypts and signs everything via a certificate.
For example it says that the email is from C.Test@a-domain.de and signed by Admin@a-domain.de.

The problem is that the other side can send encrypted to me, but I can't send encrypted to them. Because the UTM has "only" the certificate for Admin@a-domain.de. If I send an email there, it will be encrypted. But if I send an email to C.Test@a-domain.de, it will not be encrypted. Is there a way to make the UTM use the certificate Admin@a-domain.de for all addresses of @a-domain.de?

The other side uses an email gateway and therefore everything is controlled by a certificate.

Do you know a solution there?

  • Hallo,

    I've not heard of a system using a single certificate like a-domain.de.  Have you asked them how they exchange encrypted emails with other correspondents?

    Cheers - Bob
