Hi,
I run in my company a Zimbra server which serves as email server for 4 different domains. It has come to our attention that gmail recipients see this when getting an email from us:
(rima-tde.net is our ISP's, telefónica, PTR name for the server IP address)
The gmail more information link (https://support.google.com/mail/answer/ ... hl=es&rd=1) tells me that our email is being sent without TLS encryption.
As I undesrtand, in order to encrypt sent messages, I would have to set a certificate for each email domain in ZimbraAdmin > Configure > Domains > domain.com > Certificates, right?
I have tried to save there our certbot letsenctypt certificate for each domain, but I am getting the following error:
In the domain certificate field I've tried with the cert.pem alone and the fullchain.pem, both with same error.
Is there anything I am missing?
I kindly ask for your help.
If this post should be in a different subforum I'd be happy to move it.
Thanks a lot.

For information on provisioning domain certificates, to support Virtual Hosts, please reference:mkz_s wrote:Just a little bump.

FWIW, I don't use the Admin Console to do this, only the CLI.
Hope that helps,
Mark
