大家好，设置 Postfix + Dovecot + OpenSSL 后，我无法连接到我的 smtp 主机名，也无法连接到来自同一服务器的本地主机。
[root@reputation ~]# telnet reputation.host 25
Trying fe80::dad3:85ff:fe5c:e942%enp5s0f0...
telnet: connect to address fe80::dad3:85ff:fe5c:e942%enp5s0f0: Connection refused
Trying 104.219.235.10...
telnet: connect to address 104.219.235.10: Connection refused
我也尝试了端口 25、465、587，出现同样的错误
这里还有 netstat -pln
[root@reputation ~]# netstat -pln

另外，我正在努力解决，但找不到为什么会发生这种情况的原因，我错在哪里，这是我第二次尝试设置它。
此外，我希望该邮件服务器可以通过客户端 PC 邮件程序（如 gammadyne、maxbulk mailers）访问。这是我的促销邮件服务器
我希望有人能帮助我
提前致谢
答案1
禁用“仅监听环回” Postfix 配置
您的 postfix 配置为仅在 loopback/localhost 接口上接受传入的 tcp (smtp) 连接。在大多数“单用户”计算机上，将其作为默认设置是合理的。
更改inet_interfaces配置设置来改变它。
# The inet_interfaces parameter specifies the network interface
# addresses that this mail system receives mail on. By default,
# the software claims all active interfaces on the machine. The
# parameter also controls delivery of mail to user@[ip.address].
#
# See also the proxy_interfaces parameter, for network addresses that
# are forwarded to us via a proxy or network address translator.
#
# Note: you need to stop/start Postfix when this parameter changes.
#
#inet_interfaces = all
#inet_interfaces = $myhostname
#inet_interfaces = $myhostname, localhost
inet_interfaces = localhost
