Been debugging an email forwarding problem, it's basically that
the forwarder doesn't use SRS or ARC
That would be an SPF fail, but the sender domains are ~all
Why the hard bounce?
* Sender address: ~all
* The forwarded address has -all
* Receiving server rejecting with notice about sender address
SPF fail
Is the final destination server somehow taking the -all from the
intermediary address SPF?
What is it about this I'm not getting?
Is the forwarder changing the envelope sender
or *any* of the header addresses ?
