Actually, I can because I told ieee.org to forward my mail to aol.com and I know that I enabled SPF for my aol.com address. There is nothing unpredictable about that - I control both sides of the forwarding. What AOL has to predict is that some of their customers may want to forward from another mail address to their AOL mailbox and provide a way to exempt specific sender IP addresses from SPF checks. hp -- _ | Peter J.
