DKIM-過濾無簽名數據

  • March 11, 2022

閱讀本教程後,我在 Postfix 上安裝了 DKIM-Filter

我的電子郵件現在有一個 DKIM 簽名,但它仍然在垃圾郵件文件夾中。這是標題

   Received-SPF: neutral (google.com: 69.164.193.167 is neither permitted nor denied by best guess record for domain of promote@a2labs.in) client-ip=69.164.193.167;

我的 mail.err 文件也顯示

Feb 28 12:17:03 ivineet dkim-filter[32181]: 1F788530E1: no signature data
Feb 28 12:18:02 ivineet dkim-filter[32181]: 432BA530E2: no signature data

如何修復它

查看“無簽名數據”上方的行,是這樣的:

Jul  4 10:33:46 pa04 dkim-filter[29984]: 9A95B340F6C external host localhost.localdomain attempted to send as mydomain.com
Jul  4 10:33:46 pa04 dkim-filter[29984]: 9A95B340F6C: no signature data

如果是這樣,請創建文件 /etc/postfix/dkim/hosts ,其中包含要簽名的主機列表,並將以下幾行添加到 /etc/dkim-filter.conf 中:

ExternalIgnoreList      /etc/postfix/dkim/hosts
InternalHosts           /etc/postfix/dkim/hosts

dkim-filter.conf 中“域”的值是多少?在說明實際域時,我遇到了同樣的問題,並且通過使用萬用字元解決了這個問題。

從“Domain mydomain.com”到“Domain *”,保持選擇器和 KeyFile 不變。

希望能幫助到你。
