Hello. My name is Tommy Walker. I am quite new to linux, and am using Red Hat 8. This message is being sent by way of my windows machine. My linux machine receives mail with no problems. However, sending mail is not yet possible. My isp is verizon, and they require othentication. With windows, eudora is used. With linux, pine is the program of choice. Any ideas as to what I should do? Or, would anyone like more information?
