If someone uses a hosted spam filtering servic for inbound mail, then that person should turn off SPF checking on the back-end completely; checking SPF and applying policy is the job of the hosted spam filter. (If you're using a hosted anti-spam service that does *not* allow you to apply fine-grained SPF policies, then it's time to switch.) If someone uses a hosted filtering service for outbound mail, then he/she just needs to publish appropriate SPF records listing the service's egress IP addresses. Regards, David.
