[Acronym] for __S__ender __P__olicy __F__ramework [SPF] is a way of registering in [DNS] which machines are allowed to send mail from a domain. This is used to help prevent people from forging emails from people they are not, and hopefully impacting the usefulness of spam. [SPF] is implemented in [DNS] with the use of a [TXT] ResourceRecord. See http://spf.pobox.com/ for more information on SPF For [MTA] and distribution specific notes on implementing SPF, see the following: * [spf.pobox.com index|http://spf.pobox.com/downloads.html] * [exim under gentoo|http://bob.rasey.net/archives/000173.html] and [Gentoo bug request|http://bugs.gentoo.org/show_bug.cgi?id=58282] ---- CategoryDns
