When a domain publishes an SPF include for MessageGears, it establishes a trust relationship where the domain's mail authentication and reputation become partly dependent on MessageGears' infrastructure and sending practices. Poor IP reputation or compliance issues on the MessageGears side can indirectly harm mail delivery for its clients. Senders should periodically audit their SPF records and maintain clear communication with their ESP about sending volumes and list hygiene.
