帶有匹配括號的 dovecot 配置文件錯誤

當我嘗試執行 dovecot 時，出現以下錯誤。

doveconf: Fatal: Error in configuration file /etc/dovecot/conf.d/10-master.conf line 49: Expecting '{'

我查看了 /etc/dovecot/conf.d/10-master.conf 並註意第 49 行，沒有發現任何問題。

/etc/dovecot/conf.d/10-master.conf:

#default_process_limit = 100
#default_client_limit = 1000

# intended to catch and kill processes that leak memory before they eat up
# everything.

# user in Dovecot system. It shouldn't have access to anything at all.
#default_login_user = dovenull

# Internal user is used by unprivileged processes. It should be separate from
# login user, so that login processes can't disturb other processes.
#default_internal_user = dovecot

 # auth_socket_path points to this userdb socket by default. It's typically
 # used by dovecot-lda, doveadm, possibly imap process, etc. Users that have
 # full permissions to this socket are able to get a list of all usernames and
 # get the results of everyone's userdb lookups.
 #
 # The default 0666 mode allows anyone to connect to the socket, but the
 # userdb lookups will succeed only if the userdb returns an "uid" field that
 # matches the caller process's UID. Also if caller's uid or gid matches the
 # socket's uid or gid the lookup succeeds. Anything else causes a failure.
 #
 # To give the caller full permissions to lookup all users, set the mode to
 # something else than 0666 and Dovecot lets the kernel enforce the
 # permissions (e.g. 0777 allows everyone full permissions).

第 49 行：

unix_listener lmtp /var/spool/postfix/private/dovecot-lmtp {

我已經設法通過刪除該行的“/var/spool/postfix/private/dovecot-lmtp”部分來消除該錯誤，但這並不是一種解決方法，因為它可能會導致後綴集成停止工作。

我需要修復什麼才能消除錯誤消息？

您的配置行錯誤。這個lmtp詞是多餘的，該行應該是：

unix_listener /var/spool/postfix/private/dovecot-lmtp {

lmtp用於用語句表示埠號，不適inet_listener用於 Unix 套接字。
