Can't get email notifications to work

[drtech981]

This is the docker-compose file I'm using :

version: "3"
services:
  watchtower:
    image: containrrr/watchtower
    container_name: watchtower
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - WATCHTOWER_LABEL_ENABLE= true
      - WATCHTOWER_NOTIFICATIONS= email
      - WATCHTOWER_NOTIFICATION_EMAIL_FROM= watchtower-m01@services.xyzs.cc 
      - WATCHTOWER_NOTIFICATION_EMAIL_TO= admin@@xyzs.cc
      - WATCHTOWER_NOTIFICATION_EMAIL_SERVER= mail.services.xyzs.cc 
      - WATCHTOWER_NOTIFICATION_EMAIL_SERVER_PORT= 25   
      - WATCHTOWER_NOTIFICATION_EMAIL_SERVER_USER= xyzs-cc/mx-01
      - WATCHTOWER_NOTIFICATION_EMAIL_SERVER_PASSWORD= superSecret 
      - WATCHTOWER_NOTIFICATION_EMAIL_DELAY= 30

However, I'm receiving no notifications when a container updates.

Docker logs is showing :

time="2022-03-26T18:06:17Z" level=info msg="Watchtower 1.4.0"
time="2022-03-26T18:06:17Z" level=info msg="Using no notifications"

You are missing the environment: key, and I would remove the spaces between = and the value (I think it might work with the spaces, but I haven't tested it):

version: "3"
services:
  watchtower:
    image: containrrr/watchtower
    container_name: watchtower
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    environment:
      - WATCHTOWER_LABEL_ENABLE=true
      - WATCHTOWER_NOTIFICATIONS=email
      - WATCHTOWER_NOTIFICATION_EMAIL_FROM=watchtower-m01@services.xyzs.cc 
      - WATCHTOWER_NOTIFICATION_EMAIL_TO=admin@@xyzs.cc
      - WATCHTOWER_NOTIFICATION_EMAIL_SERVER=mail.services.xyzs.cc 
      - WATCHTOWER_NOTIFICATION_EMAIL_SERVER_PORT=25   
      - WATCHTOWER_NOTIFICATION_EMAIL_SERVER_USER=xyzs-cc/mx-01
      - WATCHTOWER_NOTIFICATION_EMAIL_SERVER_PASSWORD=superSecret 
      - WATCHTOWER_NOTIFICATION_EMAIL_DELAY=30
