Let's say you send me a mail to ralph@xxxxxxxxxxx That mail is just forwarded to a different mail account. Now I get a mail from someone@xxxxxxxxxxx, 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. Ralph
