Under Settings > Email Settings you configure the SMTP server that Klacks uses to send outgoing emails — such as notifications, password reset emails, or messages sent by Klacksy.

How it works​

Connection details: You enter server, port, timeout, SSL/TLS mode, authentication type (None, LOGIN, NTLM, GSSAPI, WDIGEST), as well as username and password. In addition, read receipts/delivery notifications and a reply-to address can be configured. The SSL/TLS mode is also derived from the port: port 465 uses direct SSL, port 587 (or enabled SSL) uses StartTLS.

Saving: There is no explicit save button — each field is saved automatically after a short delay as soon as you change it.

Testing the connection: The "Send test email" button establishes a real SMTP connection, authenticates, and sends an actual test email to the stored user address. This isn't a pure connectivity check but an actual mail send — useful for verifying credentials immediately. For well-known providers (Outlook, Gmail, Yahoo, GMX, etc.), Klacks strictly requires an authentication type other than "None."

Good to know​

  • This setting is global for the entire installation — there is no separate SMTP account per user.
  • Only a person with administrator rights can configure this page.
  • The password is stored encrypted and can be shown/hidden in the form via an eye icon, never displayed in plain text.
  • If the connection test fails, Klacks reports the specific reason (e.g. authentication error, SSL handshake failure, timeout) instead of a generic error message.
