Sendmail的錯誤信息：553 5.1.8 ......發件人地址的域名......不存在

Question

我安裝的sendmail服務器在本地

當我試圖仙dmail從其他電子郵件服務器我正在inhmail.walkingtree.in以下錯誤，

This message was created automatically by mail delivery software. 

A message that you sent could not be delivered to one or more of its 
recipients. This is a permanent error. The following address(es) failed: 

    mail1@inhmail.walkingtree.in 
    SMTP error from remote mail server after MAIL FROM:<srinivasa.nallapati@walkingtree.in> SIZE=2548: 
    host inhmail.walkingtree.in [122.175.35.121]: 
    553 5.1.8 <srinivasa.nallapati@walkingtree.in>... Domain of sender address srinivasa.nallapati@walkingtree.in does not exist 

------ This is a copy of the message, including all the headers. ------ 

我在192.168.1.145中安裝了sendmail服務器。 .145的域名是inhmail.walkingtree.in

我在系統和路由器的防火牆中打開了端口25。

郵件收發在192.168.1.0/24與@inhmail.walkingtree.in工作正常。

請幫助那些how sendmail can receive mails from external email servers.

工作：

是的感謝，現在它工作。

問題是我無法ping通walkingtree.in，由於settings.I在網絡連接刪除DBS服務器現在我能夠從Gmail獲得電子郵件和walkingtree.in

本地DNS服務器時，我使用DNS服務器，我能ping通www.walkingtree.in但不walktree.in。你可以請我幫我ping通walkingtree.in

Answer 1

你sendmail認爲信封發件人的域名walkingtree.in不存在（沒有MX,A, AAAADNS記錄）。它拒絕使用這種信封發件人接受郵件，因爲無法發送（最終）退回郵件（有關電子郵件傳遞問題的報告）。

您可以使用nslookup（或）來檢查服務器發現的DNS記錄：

nslookup -type=mx walkingtree.in
dig walkingtree.in MX

---

如果您使用sendmail（沒有後綴），然後爲根執行下面的命令找到問題：

echo "check_mail jd@walkingtree.in" | sendmail -d8.20 -bt 

在 「Undefined ruleset check_mail」 錯誤嘗試的情況下：

echo "checkmail jd@walkingtree.in" | sendmail -d8.20 -bt 

-d8.20打開DNS的查詢跟蹤
checkmail - 與功能使用的check_mail的當量（delay_checks）
