想請教各位大大..小弟今天發現寄給新光三越的信被退回來,結果查了一下DNS紀錄,發現有一筆10.x.x.x的紀錄在Internet DNS 上面...這樣應該會導致信件寄信的問題,對嗎?

[root@mail ~]# nslookup

server 168.95.1.1
Default server: 168.95.1.1
Address: 168.95.1.1#53
set q=mx
skm.com.tw
Server: 168.95.1.1
Address: 168.95.1.1#53

Non-authoritative answer:
skm.com.tw mail exchanger = 20 mail2.skm.com.tw.
skm.com.tw mail exchanger = 30 mail3.skm.com.tw.
skm.com.tw mail exchanger = 50 www.skm.com.tw.
skm.com.tw mail exchanger = 5 001aemw01.skm.com.tw.
skm.com.tw mail exchanger = 10 001aemw02.skm.com.tw.
skm.com.tw mail exchanger = 20 mail.skm.com.tw.
