ESA에서 아웃바운드 메일 SMTP 세션 추적
소개
이 문서에서는 Cisco ESA(Email Security Appliance)에서 전체 이메일 대화를 추적하고 보는 방법에 대해 설명합니다.
수신자 도메인당 아웃바운드 메일 SMTP 세션 추적
도메인 디버그 로그를 사용하여 ESA와 대상 도메인/호스트 간에 전체 SMTP(Simple Mail Transfer Protocol) 대화를 추적할 수 있습니다. 도메인 디버그 로그의 각 행은 SMTP 대화 중에 전송(전송) 및 수신(Rcvd)된 데이터를 간략하게 설명합니다.
ESA에서 관심 있는 수신자 도메인에 대한 도메인 디버그 로그를 기록하도록 로깅을 구성하려면 ESA CLI에 logconfig 명령을 입력합니다.
