OpenDKIM attempted to sign but there wasn't a match for the signing
domain. That is why the message was not DKIM signed. Are you using
SigningTable in your configuration.

You can do that with the MTA [1] setting in your configuration file.


1. A set of MTA names (a la the sendmail(8) DaemonPortOptions Name
parameter) whose mail should be signed by this filter. There is no
default, meaning MTA name is not considered when making the
sign-verify decision.
