GMAIL企业邮箱对应MX记录地址

前两天公司的邮箱突然无法向一个使用Gmail企业邮箱的地址发送邮件了，查了半天是因为公司邮件服务器无法连接到对方域名设置的MX记录了（Gmail的MTA），后来在域名注册商那里将不能连接的MX记录删除重新设置上可用的地址就可以了，在此记录一下。

MX 服务器地址有以下：

ASPMX.L.GOOGLE.COM

ALT1.ASPMX.L.GOOGLE.COM

ALT2.ASPMX.L.GOOGLE.COM

ASPMX2.GOOGLEMAIL.COM

ASPMX3.GOOGLEMAIL.COM

ASPMX4.GOOGLEMAIL.COM

ASPMX5.GOOGLEMAIL.COM

DNS解析设置：

设置完成后等待一会儿重启一下服务器网络，使用nslookup查看一下：

# /etc/init.d/network restart

# nslookup

 > set q=mx

 > iq-hub.com.sg

 ;; Got SERVFAIL reply from 127.0.0.1, trying next server

 Server: 10.202.72.118

 Address: 10.202.72.118#53

Non-authoritative answer:

 iq-hub.com.sg mail exchanger = 1 aspmx3.googlemail.com.

 iq-hub.com.sg mail exchanger = 1 alt2.aspmx.l.google.com.

 iq-hub.com.sg mail exchanger = 1 aspmx4.googlemail.com.

Authoritative answers can be found from:

 iq-hub.com.sg nameserver = ns1.alidns.com.

 iq-hub.com.sg nameserver = ns2.alidns.com.

 alt2.aspmx.l.google.com internet address = 74.125.25.27

 alt2.aspmx.l.google.com has AAAA address 2607:f8b0:400e:c03::1a

 aspmx3.googlemail.com internet address = 74.125.25.27

 aspmx3.googlemail.com has AAAA address 2607:f8b0:400e:c03::1b

 ASPMX4.googlemail.com internet address = 64.233.168.26

 ns1.alidns.com internet address = 42.120.221.11

 ns1.alidns.com internet address = 140.205.81.11

 ns1.alidns.com internet address = 140.205.228.11

 ns2.alidns.com internet address = 42.120.221.21

 ns2.alidns.com internet address = 140.205.81.21

 ns2.alidns.com internet address = 140.205.228.21

好了，生效了，在后台重新对邮件队列里未发出的邮件进行排队。
