Hey Carl, I think this refers to emails originating within the Salesforce Marketing Cloud (ExactTarget) platform, but the SPF missing IP and DKIM failure touch on something that I think is happening to the mail after it leaves our system. I've spun up a support case to reach out to the client and ask them if they'd like us to update the SPF record as indicated and suggesting that they review the potential DKIM configuration issue.
If a Comcast person sees this and wants to coordinate, feel free to reach out to me. Thanks for the heads up.
