+=item C<$OverrideMailPrecedence>
+
+C<$OverrideMailPrecedence> is used for overwriting the C<$DefaultMailPrecedence>
+value for a queue.
+
+The option is a hash reference of queue id/name to precedence. If you set the
+precedence to C<undef>, a Precedence header will not be added to the mail.
+
+This option only works if C<$DefaultMailPrecedence> is enabled.
