I’ve tried to browse previous posts that seem to be close to this issue, but I can’t seem to understand the fix. I apologize in advance.
I sent an email to a local government official, and got a bounceback indicating “Low Reputation Sender.” I tried a test on MX Toolbox, and it says Test: DKIM Signature Body Hash Verified, Result: Body Hash Did Not Verify.
It shows the DKIM Public Record, which I have confirmed is what shows on my MIAB Admin panel for both mail._domainkey.mydomain.com and mail._domainkey.box.mydomain.com.
Additionally, I used mail-tester.com and got the following results:
-0.1 DKIM_SIGNED Message has a DKIM or DK signature, not necessarily valid
This rule is automatically applied if your email contains a DKIM signature but other positive rules will also be added if your DKIM signature is valid. See immediately below.
0.1 DKIM_VALID Message has at least one valid DKIM or DK signature
Great! Your signature is valid
0.1 DKIM_VALID_AU Message has a valid DKIM or DK signature from author’s domain
Great! Your signature is valid and it’s coming from your domain name
0.1 DKIM_VALID_EF Message has a valid DKIM or DK signature from envelope-from domain
Any help is greatly appreciated.
