[Mailman-Users] Add PayPal to DNs publishing DMARC p=reject

$ dig +short -t txt _dmarc.paypal.com "v=DMARC1; p=reject; rua=mailto:d@rua.agari.com; ruf=mailto:dk@bounce.paypal.com,mailto:d@ruf.agari.com"

This probably is a problem of lesser magnitude than Yahoo! and AOL since few list posts will come from PayPal, or be delivered to such an address from a list. It might, however, occur by accident, or by a future change whereby PayPal account holders to use their DN, and although I can't imagine PayPal doing this, nothing seems to be sacrosanct or certain in the Wild, Wild West that is the Internet.

It's more likely that a list might add a PayPal general customer notifications address of some sort to a list, with nomail set, for the benefit of other list subscribers.
