Email

duplistatus supports sending email notifications via SMTP as an alternative or complement to NTFY notifications. Email configuration is now managed through the web interface with encrypted storage in the database for enhanced security.

Setting	Description
SMTP Server Host	Your email provider's SMTP server (e.g., smtp.gmail.com).
SMTP Server Port	Port number (typically 25 for Plain SMTP, 587 for STARTTLS, or 465 for Direct SSL/TLS).
Connection Type	Select between Plain SMTP, STARTTLS, or Direct SSL/TLS. Defaults to Direct SSL/TLS for new configurations.
SMTP Authentication	Toggle to enable or disable SMTP authentication. When disabled, username and password fields are not required.
SMTP Username	Your email address or username (required when authentication is enabled).
SMTP Password	Your email password or app-specific password (required when authentication is enabled).
Sender Name	Display name shown as the sender in email notifications (optional, defaults to "duplistatus").
From Address	Email address shown as the sender. Required for Plain SMTP connections or when authentication is disabled. Defaults to SMTP username when authentication is enabled. Note that some email providers will override the From Address with the SMTP Server Username.
Recipient Email	The email address to receive notifications. Must be a valid email address format.

A green icon next to Email in the sidebar means your settings are valid. If the icon is yellow, your settings are not valid or not configured.

The icon shows green when all required fields are set: SMTP Server Host, SMTP Server Port, Recipient Email, and either (SMTP Username + Password when authentication is required) or (From Address when authentication is not required).

When the configuration is not fully configured, a yellow alert box is displayed informing you that no emails will be sent until the email settings are filled correctly. The Email checkboxes in the Backup Notifications tab will also be greyed out and show "(disabled)" labels.

Available Actions

Button	Description
	Save the changes made to the NTFY settings.
	Sends a test email message using the SMTP configuration. The test email displays SMTP server hostname, port, connection type, authentication status, username (if applicable), recipient email, from address, sender name, and test timestamp.
	Delete / Clear the SMTP configuration.

IMPORTANT

You must use the button to make sure your email setup works before relying on it for notifications.

Even if you see a green icon and everything looks configured, emails may not be sent.

duplistatus only checks if your SMTP settings are filled in, not if emails can actually be delivered.

Security Best Practices

• Consider using a dedicated email account for notifications
• Test your configuration using the "Send Test Email" button

• Plain SMTP connections (port 25) are available for trusted local networks but are not recommended for production use over untrusted networks
