Linux가 이제 나에게 스팸을 보내고 있습니다(anacron).

약 1년 전부터 Linux Debian은 나에게 다음과 같은 스팸 메일을 보냈습니다.

(1) 단일 설정으로 이를 방지할 수 있는 방법이 있습니까? 아니면 각 스팸 유형에 대한 동기를 개별적으로 찾아 개별적으로 해결해야 합니까?

(2) 이 문제를 한 번에 하나의 스팸 메일로 해결해야 한다면 위에 붙여넣은 아나크론 문제를 어떻게 처리해야 합니까?

(3) 왜 지금 이런 일이 일어나는가? 내 데비안 컴퓨터는 적어도 6년은 됐고 약 1년 전부터 스팸을 받기 시작했고 지금 내 편지함에는 그런 이메일이 577개 있습니다.
