I believe that DMARC requires SPF. Since I want DMARC, I need to provide a compatible SPF, which means ~all.

(And I do want to implement DMARC. Not so much to improve deliverability of my own email, but rather to prevent delivery of malicious email pretending to be from my domain.)

Ok, just wondering, would "v=spf1 ?all" be the same in that case? I.e. a neutral spf policy?
