Linux下配置Dovecot常见错误及解决办法

Error: doveconf: Fatal: Error in configuration file /etc/dovecot/dovecot.conf: protocols: Unknown protocol: sieve

Dovecot Service ist nicht gestartet

[email protected]:~# /etc/init.d/dovecot restart
Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service dovecot restart

Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the stop(8) and then start(8) utilities,
e.g. stop dovecot ; start dovecot. The restart(8) utility is also available.
