min_free_space

Since: Version 2024.09.02-c5476b89

The functionality described in this section requires version 2024.09.02-c5476b89 of KumoMTA, or a more recent version.

Specifies the desired minimum amount of free disk space for the log storage in this location. Can be specified using either a string like "10%" to indicate the percentage of available space, or a number to indicate the number of available bytes.

If the available storage is below the specified amount then kumomta will reject incoming SMTP and HTTP injection requests and the check-liveness endpoint will indicate that new messages cannot be received.

The default value for this option is "10%".
