而且信件一直卡在Retry queue和 Remote queue裡面
最近在寄發信件時，信件寄發延遲現象，很久才送出，而會一直收到MDaemon
的信件通知！  Event Scheduling也預設在一分鐘。

請問各位高手我是不是有那一個地方的設定問題。可否教教我！感謝！

這個看起來是 DNS 解析不到對方的域名，但你使用的是 HiNET 的 DNS，沒有理由會解不到。不然你把 DNS 的設定改成 Google 的 8.8.8.8 及 8.8.4.4 試試看。如果還是不行，請把 DNS 查詢的逾時值設大一點，如 30 秒。

DNS 查詢的逾時值設大一點
請問是MDaemon裡面的DNS設定嗎？
如果是MDaemon的dns那我要從那個選項去設定！感謝！

MarchFun

我不知道你的是哪一版，通常在一個叫 Timeouts 中。
Wait 10 seconds for MX DNS server responses，把 10 改長一點試試。

感謝！此問題已決解！
