아래의 스크립트를 그대로 복사, 저장하거나 새로 받는다. http://kltp.kldp.org/tmp/qmail.txt 이 파일을 /etc/rc.d/init.d/ 에 qmail 이라는 이름으로 저장한 후, 실행 퍼미션을 준다.

# cp [다운로드받은 디렉토리]/qmail.txt /etc/rc.d/init.d/qmail
# chmod 755 qmail

다음 ntsysv를 실행시키면 qmail 이라는 새로운 항목이 보일 것이다. 리부팅할 때, qmail 데몬이 실행되도록 체크해준다. 당연히 sendmail 은 체크된 것을 제거한다. (레드햇 리눅스의 경우이다.)
다음은 qmail 데몬의 부트 스크립트이다.
