Function Documentation

SPF_i_done()

SPF_errcode_t SPF_i_done	(	SPF_response_t *	spf_response,
		SPF_result_t	result,
		SPF_reason_t	reason,
		SPF_errcode_t	err )

This must be called with EITHER spf_response->spf_record_exp != NULL OR result in { SPF_RESULT_PASS SPF_RESULT_INVALID SPF_RESULT_TEMPERROR SPF_RESULT_PERMERROR } or the library will abort when it tries to generate an explanation.
