소개
이 문서에서는 Cisco ESA(Email Security Appliance)를 통해 처리된 메시지 헤더를 기록하는 방법에 대해 설명합니다.
메시지 헤더를 로깅하는 방법
경우에 따라 메시지 헤더가 어플라이언스를 통과할 때 해당 헤더의 현재 상태 및 내용을 기록하는 것이 유용합니다.logconfig > logheaders를 통해 기록할 헤더를 지정합니다.ESA는 지정된 메시지 헤더를 IronPort 텍스트 메일 로그, IronPort 전달 로그 및 IronPort 바운스 로그에 기록합니다.헤더가 있는 경우 헤더의 이름과 값이 기록됩니다. 헤더 정보는 납품 정보 뒤에 기록됩니다.
다음은 헤더 X-IPAS-Result 및 X-IronPort-AV로 메시지를 기록하기 위해 로깅을 활성화하는 방법의 예입니다.
