問題：

目前所有寄yahoo的信箱都失敗.之前可以.這一二天才不行的@@~
已經爬了一堆文了.還是沒看到有人解決這個問題
目前作了一些測試

1.http://www.robtex.com/rbls.html 在這個頁面中測試了公司主機IP
沒有出現紅色警告,大多為綠色OK,一部份顯示不在白名單中.少部份顯示time out

2.檢查了 pop before smtp 設定
打勾 local sender must have accessed mailbox within last 20 minutes

打勾 Messages collected via ATRN are Exempt from this Requirement

未勾 Messages sent from trusted IPs are exempt from this requirement
(順便問一下這行的意思@@~,因為在webadmin中簡體字翻的還滿怪的)
(從下列地址發送的郵件不觸發自動回復...什麼是自動回復?)

3.http://www.abuse.net 測試open relay
看起來應該是有關閉的
Relay test 1
>>> RSET
<<< 250 RSET? Well, ok.
>>> MAIL FROM:<[email protected]>
<<< 250 <[email protected]>, Sender ok
>>> RCPT TO:<[email protected]>
<<< 550 <[email protected]>, Recipient unknown

Relay test 2
>>> RSET
<<< 250 RSET? Well, ok.
>>> MAIL FROM:<spamtest>
<<< 550 <[email protected]>, Sender unknown

Relay test 3
>>> RSET
<<< 250 RSET? Well, ok.
>>> MAIL FROM:<>
<<< 250 <>, Sender ok
>>> RCPT TO:<[email protected]>
<<< 550 <[email protected]>, Recipient unknown

4.http://www.dnsstuff.com/ 測試dns功能
回報都是pass.只有一項有錯誤
ERROR: One or more of your nameservers reports that it is an open DNS server.

5.發現 server 25 port 有被攻擊.目前已經阻擋該來源 IP,不過依舊寄 yahoo 失敗

關於寄給 yahoo，我們已經放棄嘗試了。

@@~公司在用的server說...

跟 Yahoo 的攻防玩不完的，總是無法有完整的解決方案。你去信給他請他給個方便，他們也不會理你的。

隨風浮雲

YAHOO 的信箱的確是很多問題，也許是用的人太多了，所以YAHOO被垃圾信攻擊的頻率也多，以我們公司而言100封給YAHOO的信大概一天會被檔10到15封，所以WellanShi ，你可以觀察一下所有的SMTP LOG，站長說的是正確的。

解決辦法真的是沒有，SPF DOMAINKEY 非垃圾郵件名單，大概都裝過了，YAHOO還是會莫名其妙的擋IP，為何是確定是擋IP，可從下列的LOG 看出，這些LOG顯示出YAHOO 用各種理由阻擋信件的進入，連分析信件都不分析。

所以現在都通知公司同事，要寄給YAHOO 的信箱，就去YAHOO寄吧!

我想去爭論這個問題並沒有什麼意義吧?重點是可以得到解決方案
像隨風浮雲大大碰到的問題.我現在也碰到了.沒有告知任何原因,我的IP就是被擋了.當然目前也在跟yahoo溝通中.不過我看也是機會不大吧

這是您的mail嗎?WellanShi大大

小弟我想我大概知道原因... 因為也是我切身之痛！ 我猜想原因是出在FTTB給的"動態"固定IP.. 這些IP在解析的時候都會被標注為Dynamic IP. 很多mail server對於這種註記的IP通常都會認為是垃圾信伺服器(我猜的).. 因為我公司上個月也是用FTTB的IP架mail server.. 結果很多客戶的伺服器都不收我的信... 給你猜考囉！ 我也申請反解.. 沒用！

wick

再順道提一下，有人建議我試試看將SMTP設定smart relay到HiNet的SMTP (自家的FTTB應該不會檔吧).. 不知道是否可行，因為我公司的mail server無法中斷來實驗，可能的話請開版的網友幫忙試試看，可以的話請通知我.

隨風浮雲

我們公司確定是固三IP，然後其它公司都是固一IP，自行架設DNS，另設MX記錄，但是所有信箱伺服器寄給YAHOO，都是會莫名其妙的擋IP，所以是YAHOO的問題。

另外公司這麼多人寄信，如果都轉到HINET ，那遇到一些伺服器會判定寄件者和SMTP不符就退信，那更是無解。

可否公佈不被yahoo檔的徹底解決方案,造福一下人群啦
