Sorry - the 'mail from:' address (envelope sender) is the one that is used
to detect if a DKIM signature should be added or not - not the 'FROM:'
address that is in the header .

If this is shown in the log, ASSP has successfuly checked the created
signature using your DNS records! There is nothing more I can do.

The email definitely has a FROM address. Here is an example header:

This email, when routed through the IIS SMTP server, does not get a
DKIM header added. However, the same email, sent directly to ASSP
instead of through the IIS SMTP server, gets the DKIM header added
correctly:

I did so, and it is showing the signature is OK:

However the response still shows a fail:
The results are as follows:
DKIM Signature validation: fail (verification failed)
DKIM Author Domain Signing Practices: "dkim=all"
ADSP is not required for DKIM signature validation.
So I suspect the problem may be on the DNS side, in that the
receiving mail server is not getting the key properly from DNS in
order to validate the signature?
