I've been reading over the SPF site and articles regarding the system
however one thing isn't entirely clear to me - how well the system can
help me block bounced email messages.
SPF is not meant to block bounced emails. (I just received a bounced email
because a domain supported SPF and refused a mail with a spoofed MAIL FROM).
Is there a way that I will be able to examine incoming bounce messages
using this system to validate if they actually came from my system
originally and filter those that did not?
Simply put some cookie in the return path (envelope sender) of the mail that
your system sends. And then accept only bounces that contain that cookie.
