Mail notifications in OpenCloud
This guide shows how to configure your OpenCloud instance to send notification E-Mails by modifying the .env file in your OpenCloud setup
Open the .env File
Edit the file with your preferred text editor:
nano .env
Or use vim, code, or gedit as you prefer.
Add or modify these Environment Variables
Adjust the following lines in your .env file according to your SMTP provider and requirements.
Note: SMTP_TRANSPORT_ENCRYPTION and SMTP_INSECURE may vary depending on your setup.
SMTP Settings:
SMTP_HOST=YOUR_SMTP_HOST
SMTP_PORT=1025
SMTP_SENDER=noreply@your.text
SMTP_USERNAME=YOUR_USERNAME
SMTP_PASSWORD=YOUR_PASSWORD
SMTP_TRANSPORT_ENCRYPTION=none
SMTP_INSECURE=true
SMTP_AUTHENTICATION=auto
See section Environment Variables in the developers documentation for possible values for these variables. Note, that the environment variables are prefixed with NOTIFICATIONS_, so NOTIFICATIONS_SMTP_AUTHENTICATION shows possible values for SMTP_AUTHENTICATION in the .env file.
Per default the notifications service is disabled. To send out notifications, the service must be enabled via:
START_ADDITIONAL_SERVICES="notifications"
In the .env file, values should be written without quotation marks. Do not use 'single quotes' or "double quotes" — just enter the plain value.
Save and exit
For nano, press Ctrl + O to save and Ctrl + X to exit.
Restart OpenCloud
Apply the changes by restarting the OpenCloud services:
docker compose down
docker compose up -d
OpenCloud is now successfully configured to deliver notification emails, including those triggered by actions such as file sharing.
