I am little confused when I browse the web about "postfix enable" app. basically, what I want is: to get the MAIL app to send some message to yahoo mail account, without open up the yahoo mail webpage. Then I can print it out when I go to univ. I don't have smtp server. I don't know whether I understand right or not. according to what I read if I enable the POSTFIX, and set the MAIL app to use the localhost SMTP, it will be okay.. Anyone have suggest or other method to achieve the goal. cheer.
