This signal may be emitted at any time between “envelope-from” and “end-of-message”. This signal is only emitted if the milter causes an internal error and the message processing isn't completed. For example, if the milter has already returned MILTER_STATUS_ACCEPT, MILTER_STATUS_REJECT, MILTER_STATUS_DISCARD and MILTER_STATUS_TEMPORARY_FAILURE, this signal will not emitted.

If the milter has any resources allocated for the message between “envelope-from” and “end-of-message”, should be freed in this signal. But any resources allocated for the connection should not be freed in this signal. It should be freed in “finished”.
