The problem: can no longer send outgoing email, keep getting error message "server not responding" The computer: mac mini G4 1.5, OS 10.4 The email server: eudora and thunderbird both show the same error The email settings: are accurate and have not been changed. The incoming email: is not affected and works just fine. The difficulty: a second computer, using the same internet connection, using the same email program (eudora) and the same settings is sending email successfully, so much as I'd like to blame this on the ISP, it looks like it's not their fault. I have, btw, rebooted the mini, to no avail. What do I do now?
