Linux:inet_protocols:禁用IPv6支持:地址族不支持协议

postqueue: warning: inet_protocols: IPv6 support is disabled: Address family supported by protocol

启动或者重新启动Postfix守护程序时,如何在控制台上获得这些输出警告?

postqueue: warning: inet_protocols: IPv6 support is disabled: Address family 不支持 by protocol
postqueue: warning: inet_protocols: configuring for IPv4 support only

这意味着Postfix实际上已配置为在IPv4和IPv6协议上侦听,但是在该服务器上没有配置任何IPv6地址。

要解决此问题,只需告诉Postfix严格使用IPv4。

1.编辑主要的Postfix配置:

/etc/postfix/main.cf

2.找到" inet_protocols"语句:

# Enable IPv4, and IPv6 if supported
inet_protocols = all

3.如下将" all"更改为" ipv4":

inet_protocols = ipv4

4.重新启动Postfix:

service postfix restart
