sending system in charge of a proper reaction like e.g. notifying the sender or an
administrator. If you want to be sure that no requested email gets lost, you should not
enable this option. Activate the threshold "Tag an email as SPAM when it is scored
more than" instead and make use of the features offered by the mail client programs
to sort emails based on header lines.

is rather to high than to low. Please note that automatically
