다음과 같은 문제입니다.
  ps aux를 실행시켜보니 오늘따라 눈에 않띄던게 보이더군여..
실행되고 있는 프로세스중에 평소라면
sendmail : accepti
라고 만 떠 있었는데
sendmail : ./f6dbi
라는게 떠 있더라구여 그래서 그냥 누가 메일사용하나 하고 넘어갔는데
한시간쯤 후에 다시 ps aux를 해보니까
sendmail : ./f6dbu
sendmail : ./f6dbz
sendmail : ./f6dca
이런게 계속 떠 있더라구여..
그래서 혹시 우리서버로 스팸메일 날리고 있나 하고 생각은
했었는데 제가 잘 모르는 관계로 넘어갔다가
저녁때 서버관리자 메일을 확인했더니 다시되돌아온 메일이
정확히 268개가 있더군여.. 그래서 부랴부랴
메일 로그를 확인했더니
