DKIM 未验证但 dns 记录匹配密钥

Question

努力使 DKIM 正常工作。目前这是 mail-tster 结果。

我主要缺少 DKIM 这里是我的 dns 记录。

 truebud.ca text = "truebud-64839v5873958h3ddrg._domainkey.truebud.ca k=rsa\; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQChKyCHHZEkrYfTdcB2VX0nKL8Vhicb+xQsNswOgo5+IK2ipg97VJb+lKAT+jHMXyk4KPTkUUI/8rwa2IfUKsr/BQXy6csNkmM0Y00H5/+QRAYn+ktoRWO1zXvO2sygzCELgGxcj5pHkOd4xLGhTnTpHh7UAjTp" "/swV5E18dpAubQIDAQAB"
 truebud.ca text = "v=DMARC1\; p=none"
 truebud.ca text = "v=spf1 a mx ip4:216.221.70.222 ~all"
 truebud.ca text = "_domainkey.truebud.ca o=~\; r=info@truebud.ca"

这是我的 phpmailer 代码

    $mail->DKIM_selector = $sitename."-64839v5873958h3ddrg";// change this to whatever you set during step 2
    $mail->DKIM_passphrase = "";
    $mail->DKIM_identity = $mail->From;

    $mail->send();
    echo 'Message has been sent';
} catch (Exception $e) {
    echo "Message could not be sent. Mailer Error: {$mail->ErrorInfo}";
}

我已经在这里待了一个星期了。我错过了什么？

他们的错误是：

We were not able to retrieve your public key. Please ensure that you inserted your DKIM TXT DNS record on your domain truebud.ca using the selector Truebud-64839v5873958h3ddrg.

我知道出了什么问题 — 您的 DKIM DNS 条目格式不正确。

# dig txt Truebud-64839v5873958h3ddrg._domainkey.truebud.ca
Truebud-64839v5873958h3ddrg._domainkey.truebud.ca. 120 IN TXT "truebud-64839v5873958h3ddrg._domainkey.truebud.ca v=DKIM1; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQChKyCHHZEkrYfTdcB2VX0nKL8Vhicb+xQsNswOgo5+IK2ipg97VJb+lKAT+jHMXyk4KPTkUUI/8rwa2IfUKsr/BQXy6csNkmM0Y00H5/+QRAYn+ktoRWO1zXvO2sygzCELgGxcj5pHkOd4xLGhTnT" "pHh7UAjTp/swV5E18dpAubQIDAQAB"

您在记录值中得到了主机名 - 它应该以 v=DKIM1 开头，例如：

truebud.ca text = "v=DKIM1; k=rsa\; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQChKyCHHZEkrYfTdcB2VX0nKL8Vhicb+xQsNswOgo5+IK2ipg97VJb+lKAT+jHMXyk4KPTkUUI/8rwa2IfUKsr/BQXy6csNkmM0Y00H5/+QRAYn+ktoRWO1zXvO2sygzCELgGxcj5pHkOd4xLGhTnTpHh7UAjTp" "/swV5E18dpAubQIDAQAB"

不过，我在测试的时候看到你改了，所以我猜你也发现了同样的错误！
