修复PostFix发邮件错误: Send-Mail: Warning: Inet_protocols: IPv6 Support Is Disabled

Postfix使用过程中出现如下报错，我们将网络协议指定为IP4即可.

send-mail: warning: inet_protocols: IPv6 support is disabled: Address family not supported by protocol
send-mail: warning: inet_protocols: configuring for IPv4 support only
postdrop: warning: inet_protocols: IPv6 support is disabled: Address family not supported by protocol
postdrop: warning: inet_protocols: configuring for IPv4 support only

查看当前inet_protocols

# /usr/sbin/postconf | grep inet_protocols
inet_protocols = all

修改ipv4

# vim /etc/postfix/main.cf
inet_protocols = all
改为
inet_protocols = ipv4

重启postfix

附加配置

myhostname = mail.tujie.net
mydomain = tujie.net
myorigin = $mydomain
inet_interfaces = all
# 先禁用原来的inet_protocols = all
inet_protocols = ipv4
mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain
mynetworks = 168.100.189.0/28, 127.0.0.0/8
relay_domains = tujie.net
home_mailbox = Maildir/

如果发邮件乱码，请修改默认的系统编码：http://www.quyu.net/info/648.html
