/etc/resolv.conf 里有设置正确的 DNS 服务器地址么？/var/spool/postfix/etc/resolv.conf 呢？

DNS设置没有问题，ping百度都是正常的
我在部署邮件服务器的时候按照http://iredmail.com/docs/enable.smtps.html步骤，直接开启了465端口
我在检查的时候，在/etc/postfix/master.cf把添加的命令注释掉之后，收发正常了，防火墙端口又开启，端口映射有设置。
之后，我再次把之前注释吊的恢复出来，也可以正常收发了...这个现象是为什么呢？

/etc/resolv.conf 里有设置正确的 DNS 服务器地址么？/var/spool/postfix/etc/resolv.conf 呢？
