+
+Ayon server can be configured for sending emails to users, 
+this may be used for the password recovery or by addons.
+
+
+Using Ynput Cloud email service
+-------------------------------
+
+With an active Ynput cloud subscription, emails are sent using Ynput servers
+and no configuration is necessary.
+
+
+Using SMTP
+----------
+
+Without YnputCloud subscription, a working SMTP server is required. 
+SMTP is configured using the environment variables of the server container:
+
+- `AYON_EMAIL_FROM` Email sender address (example: `[email protected]`)
+- `AYON_EMAIL_SMTP_HOST` SMTP server hostname (example: `smtp.mystudio.com`)
+- `AYON_EMAIL_SMTP_PORT` SMTP server port (example: `587`)
+- `AYON_EMAIL_SMTP_TLS` Use SSL for SMTP connection (example: `true`)
+- `AYON_EMAIL_SMTP_USER` SMTP server username (example: `mailuser`)
+- `AYON_EMAIL_SMTP_PASS` SMTP server password (example: `supersecretpassword`)
+
+When the environment variables are set properly and server is restarted, 
+you should see a "Reset password" link on the login page. 
+
+You may use that link to ensure that emails are sent 
+(don't worry, your password won't be reset, unless you change it 
+using a link in the email message).
