DKIM Validation Fails
When using Thunderbird v52+, I continually get DKIM validation errors on the receiving end. All other clients are fine (whether they also send via IMAPS or client protocols).
The exact DKIM failure: dkim=neutral (body hash did not verify)
So, Thunderbird is doing something to the body to cause failures.

Presumably you did install an extension for DKIM validation. Check with the extension author.

No, no extensions are installed. DKIM is added by my relay agent.

I don't understand this. Thunderbird does not support DKIM validation natively, it needs an add-on for this. You implied you're doing DKIM validation using Thunderbird, but how? What is your 'relay agent'?

No, I did not imply that Thunderbird did the validation. What I said was the result of the validation is always "Body hash did not verify" when sending from Thunderbird, and that all other mail clients are fine.

No, the DKIM signature is added by your relay agent *after* the message has been sent by Thunderbird. So this is not a Thunderbird problem.
My best guess is your relay agent is the problem. Note, the elements you (or your email provider) decided to include in the DKIM signing process must remain unchanged in transit, or the DKIM signature will fail authentication.
