以下電子郵件有什麼問題?

Remote Server returned '<[195.47.247.197] #5.0.0 smtp; 5.1.0 - Unknown address error 554-'5.7.1 <secretariat@debron-lovendegem.be>: Recipient address rejected: Please see     http://www.openspf.org/why.html?sender=ino%40duboccage.be&ip=195.238.6.178&receiver=mx-q.one.com' (delivery attempts: 0)>'

但是電子郵件地址存在。

我以為我已經修復了 spf 記錄,所以(不應該)是這樣。儘管如此,郵件似乎被過濾為垃圾郵件……

有誰能幫忙嗎?

郵件是從 發送的195.238.6.178,但在撰寫您的域的 SPF 記錄時顯示

v=spf1 include:spf.protection.outlook.com ip4:195.13.7.0/27 -all

發送 IP 地址不包含在 SPF 記錄中,它被配置為故障硬 ( -all)。

您應該向您的 ISP 詢問其出站郵件伺服器的地址列表(或 CIDR 塊),並將其添加到您的 SPF 記錄中。現在,您可以更改為~all最後(軟失敗)。

問題是域 (duboccage.be) 設置了一個 SPF 記錄,該記錄不允許從 發送郵件mailrelay011.isp.belgacom.be,只允許從 發送郵件mailrelay011.belgacom.be。短期解決方案是添加mailrelay011.isp.belgacom.be到 SPF 記錄:

v=spf1 include:spf.protection.outlook.com ip4:195.13.7.0/27 a:mailrelay011.belgacom.be a:mailrelay011.isp.belgacom.be -all

但是,您可能要考慮這樣一個事實,即 ISP 沒有義務為郵件伺服器保留此名稱,它可能隨時更改。為了確保您的郵件能夠送達,請使用與您的域名相關的郵件伺服器,並保證 SPF 記錄的有效性。
