我的服务器拒绝连接。注意：我正尝试从本地主机进行连接。
我正在尝试用来测试的命令：
user@hostname:~$ telnet localhost pop3
Trying ::1...
Trying 127.0.0.1...
telnet: Unable to connect to remote host: Connection refused
当我尝试使用 imap 时出现同样的错误。
这鸽舍 维基建议解决问题，但我已经尝试过修复方法。我在配置中添加了协议，并将监听选项设置为*。我的配置如下。我不确定哪里出了问题？## Dovecot 配置文件
# If you're in a hurry, see http://wiki2.dovecot.org/QuickConfiguration
# "doveconf -n" command gives a clean output of the changed settings. Use it
# instead of copy&pasting files when posting to the Dovecot mailing list.
# '#' character and everything after it is treated as comments. Extra spaces
# and tabs are ignored. If you want to use either of these explicitly, put the
# value inside quotes, eg.: key = "# char and trailing whitespace "
# Default values are shown for each setting, it's not required to uncomment
# those. These are exceptions to this though: No sections (e.g. namespace {})
# or plugin settings are added by default, they're listed only as examples.
# Paths are also just examples with the real defaults being based on configure
# options. The paths listed here are for configure --prefix=/usr
# --sysconfdir=/etc --localstatedir=/var
# Enable installed protocols

## Dictionary server settings

# Dictionary can be used to store key=value lists. This is used by several
# plugins. The dictionary can be accessed either directly or though a
# dictionary server. The following dict block maps dictionary names to URIs
# when the server is used. These can then be referenced using URIs in format
# "proxy::<name>".

您尚未为协议定义适当的侦听器。请尝试从单文件配置开始，如下所示：
## Dovecot configuration file
mail_location = maildir:/var/mail/%d/%n
protocols = imap pop3
listen = *
mail_uid = mailnull
mail_gid = mail
first_valid_uid = 26
first_valid_gid = 6
last_valid_uid = 0
last_valid_gid = 0
log_path = syslog
syslog_facility = mail
auth_mechanisms = plain
auth_socket_path = /var/run/dovecot/auth-userdb
mail_plugin_dir = /usr/local/lib/dovecot
postmaster_address = postmaster@%d
hostname = %d
sendmail_path = /usr/local/sbin/exim
lda_mailbox_autocreate = yes
lda_mailbox_autosubscribe = yes
passdb {
driver = sql
args = /usr/local/etc/dovecot/dovecot.sql
}
userdb {
driver = sql
args = /usr/local/etc/dovecot/dovecot.sql
}
protocol lda {
}
protocol pop3 {
pop3_client_workarounds = outlook-no-nuls oe-ns-eoh
}
protocol imap {
mail_plugins = quota imap_quota antispam
imap_client_workarounds = delay-newmail tb-extra-mailbox-sep tb-lsub-flags
}
