請教各位學長,是否有遇過下列的狀況及退件訊息
狀況:mailserver突然不能收發信件,而要等到我把server重新開機後,就又會變正常,這種情況在這星期已經出現兩次了。
退件訊息:如下內容敘述
Hi. This is the qmail-send program at ektrontek.com.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.
<[email protected]>:
Sorry, I wasn't able to establish an SMTP connection. (#4.4.1)
I'm not going to try again; this message has been in the queue too long.
我並沒有查到這一類的錯誤訊息,為什麼會有這樣的情況呢?
煩請各位學長指點
謝謝
