I have this problem on mail in leopard it will pop up and ask for me to re-enter my password every day but when it does it doesn't stop so i have to click cancel and remember to click "get mail" later on as it stops checking every 5 mins because it takes the account offline when i click cancel. If i click "get mail" later on it will work again for a while and then maybe 2 hours later it will pop up again asking for my password agian. A few things to note: My password and the server name are all correct because it does download the mail when it wants too, It can't be yahoo's servers this has been going on for like 3 months now and it didn't happen in tiger. Ive tried the following and non of them have worked: Repairing the keychain, Deleting the password from the keychain and re-entering the password in mail. Does anyone have a solution to this?
