Expired Lets encrypt certificate for mail.mydomain.org

[maja2020 (MvO)]

NethServer Version: latest core version
Module: mail 1.7.12

The expired certificate mail.mydomain.org on node must be immediately renewed or removed from the TLS certificates page.

This certificate was created at install time (18 months ago). Now, the server lives behind a WAF so Traefik is unable to renew this certificate. TLS cert for the external mail address is present on the WAF.

If I try to remove the certificate (settings - TLS certs) on the node, it says “remove certificate for ?” on the validation screen. The name seems invalid and no matter what I try the delete confirmation button never enables.

Is it possible to remove the certificate manually?

Normally, the certificate is requested and issued together with the node’s certificate. If you click the three dots on the right side of the “Node” tab (usually the top one) in the TLS Certificates section, the “Manage Names” window will open. There, you should be able to remove the FQDN for the mail server. A new certificate should then be issued for the host without the mail server. I think…
