Hello everyone,
we have set up a new open-xchange email server.
Everything is running cleanly. Gmail also recognizes the emails properly and they don’t end up in spam.
However, when we tested an email we had an error:
Certificate #1 of 1 (sent by MX):
Cert VALIDATION ERROR(S): unable to get local issuer certificate
This may help: What Is An Intermediate Certificate
So email is encrypted but the recipient domain is not verified
We cannot find the config and the path in which the intermediate certificate must be stored.
Please help!
