Hi !!
I have read up about SPF and I have a concern with eBay messages. I know
that eBay forges the headers to show that the sender is the from address.
I also know that once SPF goes full Deny, how will eBay be able to send
these messages again?
without any problem, eBayonly forges the headers, not the envelope sender
which is what spf tests.
The same thing applies to mailing lists, such as this one.
I wish it really wouldn't be "without any problem", but,
unfortunately, there are a lot of broken mailing lists software out
there along with a huge number of broken MTAs that don't report the
envelope from to the end user so that the user can detect when it is
wrong. The fundemental problem with all systems that tighten up
requirements is that it exposes systems that are broken.
