后缀，不能通过telnet连接

设置Postfix + Dovecot + OpenSSL后，大家好，我不能连接到我的smtp主机名，也不是从同一台服务器的本地主机。 

[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

我也尝试端口25,465,587相同的错误

这里也是netstat -pln

您的后缀被configuration为只接受传入的tcp（smtp）连接在loopback / localhost接口上。 这在大多数“单用户”计算机上是默认的。

更改inet_interfacesconfiguration设置以更改它。

您的master.cf文件 ： 

 # 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
