各位老大,今天在网上,想看看大公司的邮件是怎么做的,所以就nslookup了一下ibm。com的MX记录,发现ibm的mx的值都是设的10,只是服务器不一样,有那位老大了解它这个是什么意思吗?有什么用处吗?
ibm.com MX preference = 10, mail exchanger = e5.ny.us.ibm.com
ibm.com MX preference = 10, mail exchanger = e6.ny.us.ibm.com
ibm.com MX preference = 10, mail exchanger = e31.co.us.ibm.com
ibm.com MX preference = 10, mail exchanger = e32.co.us.ibm.com
ibm.com MX preference = 10, mail exchanger = e33.co.us.ibm.com
ibm.com MX preference = 10, mail exchanger = e34.co.us.ibm.com
ibm.com MX preference = 10, mail exchanger = e35.co.us.ibm.com
ibm.com MX preference = 10, mail exchanger = e1.ny.us.ibm.com
ibm.com MX preference = 10, mail exchanger = e2.ny.us.ibm.com
ibm.com MX preference = 10, mail exchanger = e3.ny.us.ibm.com
ibm.com MX preference = 10, mail exchanger = e4.ny.us.ibm.com
ibm.com nameserver = ns.austin.ibm.com
ibm.com nameserver = ns.watson.ibm.com
ibm.com nameserver = ns.almaden.ibm.com
ibm.com nameserver = internet-server.zurich.ibm.com
