테스트 하던 중 웹메일로 보내면 기존 회사메일로 들어오지 않아서
기존 회사 메일서버 로그를 확인해 보니 이상한 점이 있네요.

보시는 바와 같이.. SMTP 연결 경로가 틀립니다.
아마도 admin페이지에서 제가 설정한 SMTP서버를 거치지 않고 와이즈기가(?)의 서버를 거치는 듯 합니다.
더욱이 spamhaus에서 블럭된 IP네요... 그래서 회사 메일서버로는 들어오지 않는듯 합니다.
spamhaus에서 검색해서 필터링하게 되어있거든요.

그 외에도 몇가지 admin 설정에서 문제가 있는 듯 합니다....
이건 조만간 정리해서 올리겠습니다. 내부 OS세팅에 상당히 문제가 있다고 판단됩니다.
