That would require the receiving mail server to check SPF.  Many don't, but we find it useful.

I noticed the majority of other email admins arn't even Running spf..   for example: nremc.com   then, there are the 1,000,000,000,000 hosts that don't even have postmaster or abuse even setup.     ----- Original Message ----- From: Darin Cox To: Declude.JunkMail@declude.com Sent: Tuesday, April 26, 2005 9:57 AM Subject: Re: [Declude.JunkMail] DNS SPF Record We use it.  For us the main benefit is to keep spammers from forging our customers' domains.  SPF tells us when the mail server sending the email from one of our customer's domains is not ours.  Works very nicely, and also is used as another bit of evidence to other email admins (since they often cannot be troubled to read the email headers...no one on this list, though <grin>) that the forged spam they received really did not originate from our servers.
