You have one account but several smtp servers, including one on the incoming inbound.att.net. Remove all but the Default one and see if sending works.
The problem might have been caused by the sending account using the wrong smtp (select the account on the left, note the selected smtp on the right for Outgoing Server (SMTP)).
