Handling of -all

2005-02-09 14:34:50
I think we're all aware that SPF does not work well with message forwarding (college alumni addresses and the like). Given that's the case, how should -all be handled? Two possibilities I can think of:

(1) Originating domains that potentially send through forwarders should not publish a -all policy, since some recipients might inappropriately reject forwarded messages. Since it's hard to know what addresses are forwarded, -all policies would probably be quite rare.

(2) SPF verifiers should not reject mail that does not match a -all policy, because of the possibility it came through a forwarder.

In other words, should the domain publish a gentler policy to allow for forwarders or should recipients apply a gentler response?
