What Scott described in his recent posting to spf-devel is known as "outbound SPF checking". I am practicing this myself (as a stop-gap measure until I manage to implement full MAIL FROM authorization), and I think we should describe the concept on the SPF website, say, on an "Outbound SPF Checking" page. Is someone of those listening and knowledgeable of the concept willing to write a concise description of it? I'd do it, but I'm overloaded at the moment. (If you are willing but don't have write access to the website, either ask for it, or just post the text on this mailing list, then one of the webmasters will pick it up.) -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.3 (GNU/Linux) iD8DBQFE50gYwL7PKlBZWjsRAhRMAJ4sk00qtNaaYLHdRB7hqpA+X1/JGwCcCW7/ ggrPg9IRyg0oGw/FHFbixC4= =TGp7 -----END PGP SIGNATURE----- ------- To unsubscribe, change your address, or temporarily deactivate your subscription, please go to http://v2.listbox.com/member/[EMAIL PROTECTED]
