我認為這是 domain 商代它設定的 mail server 的地址,像我自己也是這樣,請看我下列圖示:
Basically, to get domain's MX records from DNS, for example xxx.com, we should only check xxx.com, not mail.xxx.com.
Okay, take a domain xxx.com as an example, Let say, if there are three mail exchangers available for xxx.com, how do you check it? mail00.xxx.com mail01.xxx.com or anything else. obviously, we just only check xxx.com. Therefore, your checking is already wrong at the very beginning.
My domains are also parked at foreign DNS servers but I haven't seen any preset record from them up to now. |
