hello, i have an older power mac G5 running 10.5.8. Lately, my icloud (mobile me, mac mail, whatever we call it ) stopped working. It won't send or receive mail. I have the little exclamation mark in the triangle, inside the circle next to the account name. I've been messing with the settings. I'm trying to set the incoming mail server to imap.mail.me.com, but as soon as i save, and close out, and go back to that page, it goes right back to mail.mac.com. Can't find a solution online. Any help would be appreciated. Thank you!
