这是我们公司我在公司内部看出来的记录
htsemi.com MX preference = 10, mail exchanger = shsmtp.htsemi.com
htsemi.com MX preference = 5, mail exchanger = tpex01.htsemi.com
shsmtp.htsemi.com internet address = 192.168.10.129
tpex01.htsemi.com internet address = 192.168.2.5

yahoo.com MX preference = 1, mail exchanger = mx1.mail.yahoo.com
yahoo.com MX preference = 1, mail exchanger = mx2.mail.yahoo.com
yahoo.com MX preference = 1, mail exchanger = mx3.mail.yahoo.com
mx4.mail.yahoo.com internet address = 68.142.202.12
mx4.mail.yahoo.com internet address = 66.218.86.156
mx4.mail.yahoo.com internet address = 67.28.113.19
mx4.mail.yahoo.com internet address = 68.142.202.11请问这2者有什么区别呀？
麻烦大哥大姐给我解释一下，或者给我些资料看看。
我们公司的邮件按照我理解先应该到tpex01.htsemi.com
因为他们mx preference的优先级比较高。
那么ｙａｈｏｏ．ｃｏｍ它有‘好几个MX preference = 1 它的邮件是怎么走的啊？
