綁定 DNS 問題
我已經為我的網站 winpack.cf 設置了綁定 DNS 伺服器，但似乎出了點問題：mxtoolbox 顯示“在 2 個名稱伺服器超時或非權威響應後查找失敗”…
我有 Ubuntu 14.04，我認為配置中最奇怪的可能是一個問題（儘管我認為它不應該）是名稱伺服器和主網站的 IP 相同。（意味著我在同一台電腦上配置了 Apache 和 Bind）
我已經配置了適當的膠水記錄，我確定。
我在 BIND 上的區域配置文件是：
; ; BIND data file for winpack.cf ; $TTL 604800 @ IN SOA winpack.cf. winpackjason.outlook.com. ( 2015020201 ; Serial 7200 ; Refresh 7200 ; Retry 2419200 ; Expire 900 ) ; Negative Cache TTL IN A 2.84.10.240 ; @ IN NS ns.winpack.cf. ns IN A 2.84.10.240 @ IN A 2.84.10.240 @ IN MX 10 winpack.cf. @ IN TXT "v=spf1 mx a -all" www IN CNAME winpack.cf.“dig +trace +additional winpack.cf”的輸出：
