如何让 exim4 拒绝其他 IP 使用服务器发送邮件?

如何使 exim4 仅允许 smtp 连接从 127.0.0.1 发送邮件。但同时也接收邮件。我对此感到困惑,因为如果我更改dc_local_interfaces127.0.0.1,它无法接收邮件,但只允许 127.0.0.1,这正是我想要的。但是,我还想从互联网接收邮件,而它只允许 127.0.0.1 发送邮件。

我在用 Ubuntu。但我认为这可能与 Ubuntu 没什么关系。

更新-exim4.conf.conf

# /etc/exim4/update-exim4.conf.conf
#
# Edit this file and /etc/mailname by hand and execute update-exim4.conf
# yourself or use 'dpkg-reconfigure exim4-config'
#
# Please note that this is _not_ a dpkg-conffile and that automatic changes
# to this file might happen. The code handling this will honor your local
# changes, so this is usually fine, but will break local schemes that mess
# around with multiple versions of the file.
#
# update-exim4.conf uses this file to determine variable values to generate
# exim configuration macros for the configuration file.
#
# Most settings found in here do have corresponding questions in the
# Debconf configuration, but not all of them.
#
# This is a Debian specific file

dc_eximconfig_configtype='internet'
dc_other_hostnames='mydomain.com'
dc_local_interfaces='0.0.0.0 ; ::0'
dc_readhost=''
dc_relay_domains=''
dc_minimaldns='false'
dc_relay_nets=''
dc_smarthost=''
CFILEMODE='644'
dc_use_split_config='false'
dc_hide_mailname=''
dc_mailname_in_oh='true'
dc_localdelivery='mail_spool'

由于 stackexchange 字符限制,我无法发布 exim4.conf.template,抱歉。

答案1

在默认的 exim4 配置中,relay_from_hosts列表确定哪些主机可以从您的服务器发送邮件。请参阅 Exim 文档:

答案2

我刚刚因为这个而改用了 postfix。
