The validity of the signature in the MDN receipt.
This property contains the status of the signature verification attempted by the adapter. The following values may be returned:
|Valid||A valid signature was included in the MDN Receipt.|
|Invalid||A signature was included in the MDN Receipt, but was either invalid or could not be verified with the provided certificate.|
|None||No signature was included in the MDN Receipt.|
It is recommended that you check this values in your orchestration to ensure that the MDN is signed as expected and contains a valid signature. Ordinarily, only "Valid" results indicate a successful MDN, but if you have requested an unsigned MDN by setting the MDNOptions configuration setting, "None" is also an acceptable value.
This property is not available in the Sender.
