Unable to get email notifications working: notification service 'email' is not supported"

[trudesea]

Hi,

I just started using argocd a few days ago. I'm having an issue getting emaill to work. I have an smtp that does not require authorization. My configmap is as follows

apiVersion: v1
kind: ConfigMap
metadata:
  name: mycosmtp
data:
  service.email.myco: |
    host: smtp.myco.com
    port: 25
    from: [email protected]

apiVersion: v1
kind: ConfigMap
metadata:
  creationTimestamp: null
  name: argocd-notifications-cm
data:
  subscriptions: |
    - recipients:
      - email:[email protected]
      triggers:
      - on-sync-succeeded
      - on-sync-status-unknown
      - on-sync-failed
      - on-health-degraded
      - on-deployed
      - on-deleted
      - on-created
      - on-sync-running

I am getting this error in the gke logs:

textPayload: "time="2022-08-04T18:07:16Z" level=error msg="Failed to notify recipient {email [email protected]} defined in resource argocd/cd-jenkins: notification service 'email' is not supported" resource=argocd/cd-jenkins"
timestamp: "2022-08-04T18:07:16.445265636Z"

What am I missing here?

Thanks
