Hello, As a followup of my previous question, I would like to get some clarification about Source-IP (as shown in failure reports for example). My setup is described below:

How can I be sure that it won't play against me? I can't understand the source code of OpenDMARC, so I can't be sure the verification process won't use that IP address, for example for SPF, even though SPFIgnoreResults is set to false.
