I am adding a SPF to my GoDaddy account and I am new to writing an SPF. I have my outlook mail server through mailstreet and they gave me a few IP addresses to add and told me to use? all at the end. Then when i go through the (wizard http://old.openspf.org
) they add ~all instead - salesforce request us to add ~all too. My email campaigns are sent through exact target an they add -all in their SPF example. Can i add both? "?all" after the ip addresses and "~all" after the include: section?
How does ?all affect deliverability or how spam blockers identify my mail?
