mail server的問題 - BBS

從外面的郵件伺服器寄到自己的伺服器
有時候 會出現

Technical details of temporary failure:
TEMP_FAILURE: Could not initiate SMTP conversation with any hosts:
[211.21.69.19. (10): Destination address required]

這樣的error message

看了一些文章
似乎是DNS設定的問題

於是dig mx comdek.com
出現
; <<>> DiG 9.3.1 <<>> mx comdek.com
;; global options: printcmd

這樣的MX record有錯誤嗎?
還是哪裡的問題呢?因為這樣的error message不是每次都出現...
感謝各位!
