Ive searched and found similar posts but I thought Id start a new one. I Have been using the mac mail application with my godaddy free email account for probably 4 years now never having any real problems. all of a sudden my out going mail will not work and the application says my password is invalid and repeatedly asks for me to enter my password but does not accept it. Now i did not make any changes so this should not have happened? Steps taken to try to fix issue: 1. Try both outgoing mail on phone and web-based email. Both work which points finger at the application. unsuccessful 2. Changed password and reset keychain. unsuccessful 3. Tried creating a different account on another mac. unsuccessful 4. Genius bar. They couldnt figure it out and pointed finger at GoDaddy 5. Called GoDaddy support they pointed finger at mac. I am positive that the pass and user info are correct. Does anyone know how to resolve this? It is very frustrating and I really like the mail app until now. Please help thanks in advance!
