Looking through my notes, I see one report of an IETF list where a sender who hadn't read RFC 5617 sent mail from a discardable domain, and a recipient who also hadn't read RFC 5617 rejected rather than discarding on discardable missing signatures, and got themselves bounced off the list. The resolution for for the sender to say oops, and delete their ADSP record.
On this list we used to see mail from paypal.com, which also publishes discardable, but as far as I can tell, it didn't cause any problems in practice. Our Paypal subscribers now use a different domain for their list mail. Has anyone else seen any actual observed interactions between ADSP and mailing lists?
