Others have addressed DKIM, but for SPF I have found that every message to a mailing list of any size generates a number of reports of SPF failures, even though the list has correctly used its own domain in the envelope return path. I believe this is because there are people or bots subscribed to the list using terrible mail-forwarding configurations, where the forwarded message is sent with an envelope sender extracted from the From: header field - either because the software is a disaster, or because it's being used on a machine that cannot or does not properly record the original envelope when delivering received messages.
