- 메시지를 보낸 이메일이 수신되어야 합니다.
local_smtp
- 로컬 네트워크의 다른 컴퓨터에 SMTP 서버를 설치하고 들어오는 모든 메일을 다음 컴퓨터로 전달하십시오.external_smtp
external_smtp

특정 이메일의 이메일만 수락 하도록 이메일을 추가로 전달해야 하는 사용자/비밀번호로 이메일을 보내고 sender_email
인증하도록 sendmail을 구성했습니다 . 이 경우에는 그렇습니다. 그러나 로그 파일에 따르면 인증에는 sendmail이 대신 사용됩니다 . 를 통해 인증하고 싶지 않습니다 . 왜냐하면 에 따라 다르기 때문입니다 .local_smtp

다음 테스트의 가능한 결과를 정의합니다.
- 인증 정보 조회 없음
- 예상한 것과 다른 키를 사용하여 authinfo 조회
- authinfo 조회에서 "일치 없음"이 반환됨
- authinfo 조회가 올바른 값을 반환합니다.
