Please help.&nbsp; Somehow the yahoo is blocking our company smtp probably because it is anonymous (simple smtp with no domain ID setup).&nbsp; I tried to use yahoo bizmail but it does not work.&nbsp; I think it needs to use different port and SSL enable.&nbsp; Can someone tell me where to change that and how?&nbsp; Thank you. <br>
