sohu的MX记录
> set type=mx

sohu解决析出来 mail exchanger=域名
Non-authoritative answer:
sohu.com MX preference = 10, mail exchanger = sohumx.sohu.com
sohu.com nameserver = ns2.sohu.com
sohu.com nameserver = dns.sohu.com
sohu.com nameserver = ns1.sohu.com
sohumx.sohu.com internet address = 61.135.132.100
dns.sohu.com internet address = 61.135.131.86
ns1.sohu.com internet address = 61.135.131.1
ns2.sohu.com internet address = 61.135.132.1
> mail.sohu.com
Server: ns.fhnet.cn.net
Address: 202.99.8.1
mail.sohu.com
primary name server = ns.mail.sohu.com
responsible mail addr = lilywu.sohu-inc.com
serial = 2004032401
refresh = 3600 (1 hour)
retry = 900 (15 mins)
expire = 43200 (12 hours)
default TTL = 600 (10 mins)
为什么我们的邮件服务器解析出来是IP地址呢？
> set type=mx
> mail.real.com.cn
Server: ns.fhnet.cn.net
Address: 202.99.8.1
Non-authoritative answer:
mail.real.com.cn MX preference = 10, mail exchanger = 219.238.33.32
c-real.com.cn nameserver = ns3.sanfront.com.cn
ns3.sanfront.com.cn internet address = 210.72.13.83
