Can't email to Verizon, AOL or Yahoo from Godaddy account. Logged in to Godaddy webmail so its not the client. Logged in from several locations. Made new Godaddy emails on the same domain. Domain is not listed in RBL blocking anywhere. Godaddy says their mail servers are fine. CAN send to all three other ISPs from several other email addresses which are not on Godaddy.
