What, you don't want to trust all of Apple's /8? Anyways, adding spf for an entire cloud provider of generic tools seems like a really bad idea. We have to make sure with ours that we don't let people cross domain forge, since they may then spf pass... If you don't control the software, it is unlikely you can really control that ... Unless you control the relay or DPI or something. On Apr 14, 2016 11:16 AM, "Michael Peddemors" <mich...@linuxmagic.com> wrote:
SPF is a decent tool, however it always surprises me when banks open their SPF records to the point where they are at risk. In just the last couple of days, we see a couple of banks adding to their SPF records, 'all IP(s) in our cloud providers network /16'. Now, (in the latest case most of MicroSoft's Azure) maybe that is what they are recommended to do, however anyone else using those IP(s) is now in a perfect position to take advantage of this.. :( -- "Catch the Magic of Linux..." ------------------------------------------------------------------------ Michael Peddemors, President/CEO LinuxMagic Inc.
