Configuring email server

Mail server can be configured during NetBackup installation by including the name of the configMap in the emailServerConfigmapName field of the environment.Spec in helm/cloudscale/cloudscale-values.yaml file.

The configMap data must have entries in a key: value form to configure the mail server, as shown below for smtp field:

emailServerConfigmap
apiVersion: v1
kind: ConfigMap
metadata:
name: configmail
namespace: <netbackup-namespace>
data:
  smtp: "xyz.abc.domain.com"
  smtp-use-starttls: ""

If there is a specific parameter that needs to be set only (not value), a key can only be specified with the smtp-use-starttls field.

Perform the following to modify the mail server settings:

Exec into the primary container using the following command:
kubectl exec -it -n <namespace> <primaryServer-pod-name> -- bash
Update the persistent file at /mnt/nbdata/usr/openv/etc/mail.rc to set the fields as required.

If the emailServerConfigmapName field in the environment.Spec, is left empty (""), then the mail server would not be configured automatically as a part of NetBackup installation. In such case, the user will have to configure it manually post installation by performing the following steps:

Exec into the primary container using the following command:
kubectl exec -it -n <namespace> <primaryServer-pod-name> -- bash
Execute the following commands in the primary container:
mv /etc/mail.rc /mnt/nbdata/usr/openv/etc/mail.rc
ln -nsf /mnt/nbdata/usr/openv/etc/mail.rc /etc/mail.rc
Update values for required fields at /mnt/nbdata/usr/openv/etc/mail.rc. An example of mail.rc file is shown below:
```
mail.rc
# mail server configuration
set mail
set mailserver=xyz.abc.domain.com:25
set smtp-use-starttls
```
