And IMHO, if I'd need to say it's useful it's because it's not as extended as it may be; if everyone had configured the verification of SPF, mail forging would be reduced a lot. I use it both for personal and profesional purposes, at work we have rules for analyzing SPF results and it really helps. Definitely recommendable. Regards.
