답변1
미안합니다위에 오해의 소지가 있는 댓글. sasldb를 사용하면 실행할 필요가 없습니다 saslauthd . 따라서 시작 스크립트에서 안전하게 제거할 수 있습니다. 다음과 같은 경우 saslauthd를 실행해야 합니다.시스템 사용자, LDAP 또는 원격 IMAP을 통해 비밀번호 확인을 수행합니다..
saslpasswd2첫 번째 단계는 바이너리를 사용하여 sasldb용 데이터베이스를 생성하는 것입니다.
# saslpasswd2 -c [email protected]
Password:
Again (for verification):
sasldblistusers2를 실행하여 확인하십시오.
# sasldblistusers2
[email protected]: userPassword
이렇게 하면 데이터베이스가 sasldb2 파일에 저장됩니다. 내 시스템의 파일은 /etc/sasldb2. 그것을 읽으려면 (SASL 라이브러리를 통해) postfix가 필요하기 때문에 postfix가 그것을 읽을 수 있도록 이 파일의 그룹 변경을 추가하십시오.
# ls -l /etc/sasldb2
-rw-r----- 1 root root 12288 Feb 27 06:09 /etc/sasldb2
# chgrp postfix /etc/sasldb2
# ls -l /etc/sasldb2
