수고 많습니다.

웹서버와 이메일 서버를 분리하여 사용 중이고, 웹서버에서는 smtp 주소에 이메일 서버의 물리적인 아이피를 입력하여 사용 중인데, 그렇다면 웸서버에서는 Postfix Mail Server는 가동하는 것이 맞을 것 같고, Dovecot IMAP/POP3 서비스는 죽이는 것이 맞는 것 같은데, 현재는 가동중인 상태입니다.

웹서버에 secure log에 알 수없는 로그가 잔뜩 쌓이고 서버의 반응 속도가늦는 것 같고 해서 살펴보는 중인데, 이런 의문이 들었습니다.

참고로 아래에 secure 로그의 일부를 인용합니다.

운영 중인 서버라 조심스러워서 미리 조언을 구합니다.

IMAP/POP 서비스 죽이는 것이 맞는지 어떤지 알려주시면 고맙겠고, 아래의 로그에 대해서는 어떤 조치를 하는 것이 좋을 지 조언해주시면 갑사하겠습니다.
