Why? An SPF query either passes or fails (in the narrow sense that a
connection is either REJECT-ed/TEMP-failed or passed through). If it
passes, then there is, thereafter, no longer a reason to send a bounce
based on the result of the SPF-query. Right?
An SPF query could result in a "SOFTFAIL", and that result should be passed
on to the final recipient's spam filter. A bounce might come as late as
several hours, when the recipient hits a "Reject as Spam" button. That
reject should be treated as a "bounce" and follow authenticated addresses
all the way back to its source.
How do you currently handle soft fails?
