寄信到某公司email都會被退

各位大大好

目前只有寄信到某個國外公司的信箱
會被退信
首先會先收到Undelivered Mail Returned to Sender通知信
Reporting-MTA: dns; mx1.dnsmadeeasy.com
X-Postfix-Queue-ID: E00992B83B47
X-Postfix-Sender: rfc822; [email protected]
Arrival-Date: Wed,  2 Nov 2016 02:38:02 +0000 (UTC)

Final-Recipient: rfc822; [email protected]
Original-Recipient: rfc822;[email protected]
Action: failed
Status: 5.0.0
Remote-MTA: dns; mail.mexxxxxx.com
Diagnostic-Code: smtp; 550 failed to meet SPF requirements


然後我查一下SMTP-OUT的log紀錄

Wed 2016-11-02 10:11:26: --> QUIT

其中有出現這段
550 Message does not pass DomainKeys requirements for domain xxx.com.tw
請問這是對方主機因為Domainkeys沒驗證過
退我方信的意思嗎?


請問我是要自己在主機上設定什麼?
還是請對方不要檢查Domainkeys


感謝大家

為你的郵件主機加上 Domainkeys 的設定。急用的話，請對方關閉 Domainkey 的檢查。
