    Advanced Configuration for Mail delivery

    IntroductionPermanent link for this heading

    Outgoing email (for example app.telemetry notifications) can be deliviered using a so-called smarthost or relayhost. It is possible to configure this in the management center in SMTP-Settings.
    Some email servers however require additional configuration.

    Configuration of Advanced SettingsPermanent link for this heading

    Advanced settings for the service responsible for email delivery (postfix) are read and applied on service startup from all files in /config/postfix with the .conf extension.

    Changes in those files are only applied after a restart of the postfix service and are persistent across product updates.

    systemctl restart postfix.service

    Use-Case: Setup SMTP AuthenticationPermanent link for this heading

    Some email servers only relay emails after successful authentication. In this case the following settings in /config/postfix/override.conf can be used to set this up.

    smtp_sasl_auth_enable = yes
    smtp_sasl_tls_security_options = noanonymous
    smtp_sasl_password_maps = hash:/config/postfix/sasl_pass.map

    The required credentials need to be placed in the file /config/postfix/sasl_pass.map using the following format:

    hostname_of_the_relay username:password

    Currently the following methods are supported for authentication and are automatically negotiated with the mailserver: PLAIN, LOGIN
