질문
어떻게 Whitelist a Trusted Sender(신뢰할 수 있는 발신자를 화이트리스트에 추가합니까)?
답변
이 발신자 그룹은 $TRUSTED 메일 플로우 정책을 사용하므로 Cisco ESA(Email Security Appliance)에서 신뢰하는 발신자를 WHITELIST 발신자 그룹에 추가합니다. WHITELIST 발신자 그룹의 구성원은 속도 제한이 적용되지 않으며, 이러한 발신자의 콘텐츠는 Cisco IronPort AntiSpam 엔진에서 검사되지 않지만 Sophos Anti-Virus 소프트웨어에서 검사됩니다.
참고: 기본 컨피그레이션에서는 안티바이러스 검사가 활성화되지만 안티스팸은 해제됩니다.
발신자를 화이트리스트에 추가하려면 발신자를 HAT(Host Access Table)의 WHITELIST 발신자 그룹에 추가합니다. GUI 또는 CLI를 통해 HAT를 구성할 수 있습니다.
GUI에서
- Mail Policies(메일 정책) 탭을 클릭합니다.
- Host Access Table(호스트 액세스 테이블) 섹션에서 HAT Overview(HAT 개요)
- 오른쪽에서 InboundMail 리스너가 현재 선택되어 있는지 확인합니다.
- 아래 Sender Group(발신자 그룹) 열에서 WHITELIST(화이트리스트)를 클릭합니다.
- 페이지 하단의 Add Sender(발신자 추가) 버튼을 클릭합니다.
- 첫 번째 필드에 화이트리스트에 추가할 IP 또는 호스트 이름을 입력합니다.
항목 추가를 완료하면 Submit(제출) 버튼을 클릭합니다. 변경 사항을 저장하려면 Commit Changes 버튼을 클릭해야 합니다.
