Updating
Either follow the instructions of the used installation guide, or update only Kolab.
Transitioning to a new certificate
A new Kolab instance is generally deployed with a self-signed certificate. It is recommended that you transition to a non-self signed certificate that is either obtained manually or via letsencrypt.
Backup & Restore
Backup & Restore procedures differ depending on how Kolab is deployed. Either follow the instructions of the used installation guide or use the generic instructions here to back-up Kolab only.
Standard operating procedures
Undeleting email
Emails are only truly deleted (expunged) after 28 days. In the meantime email can be restored like so:
kubectl exec -ti deployments/imap -- unexpunge -adv user/user@example.com
To list emails available to be restored:
kubectl exec -ti deployments/imap --unexpunge -l user/user@example.org
For more information see the upstream documentation.
