No, I'm very sure about SPF. It's crap. Utter crap. And it can break mails
in a very funny way.
Let's say you send me a mail to ralph at centos.org. That mail is just forwarded
to a different mail account. Now I get a mail from someone at hoffman.com, but
I get it via mail.centos.org which clearly isn't a server you would allow to
send mails out as @hoffman.com when you set up SPF for your domain. So if I
drop mails which don't have a "correct" SPF record - I'd drop that mail.
Although your domain has correct SPF records.
And yes, there are ways around it which make the whole thing even uglier.
