nice! but DMAchoice has no effect on EDDM delivery, it only affects mail that is directly addressed to you. anything addressed to Postal Customer, Residential Customer, or any of the other names they use can not be stopped. Even if you put a sign on the mailbox that says 'No Junk Mail', a postal carrier is legally obligated to deliver EDDM correspondance to every stop on their route
