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
修改方法:
/usr/sbin/postconf | grep inet_protocols --查看当前的inet_protocols
inet_protocols = all
vi /etc/postfix/main.cf
inet_protocols = all
改为inet_protocols = ipv4
重启/etc/init.d/postfix restart
crond: postdrop: warning: unable to look up public/pickup: No such file or directory
Turns out that sendmail was previously installed and that was messing things up. I had to stop sendmail and make the appropriate directory and restart postfix.
结果发现之前安装了 sendmail，这把事情搞砸了。 我不得不停止 sendmail 并创建适当的目录并重新启动 postfix。
mkfifo /var/spool/postfix/public/pickup
ps aux | grep mail
kill PID
sudo /etc/init.d/postfix restart
--》没有使用postfix，可以忽略该提示？？
