New to the Mac world and having a peculiar problem. Have Mac Book Pro running OSX 10.5.7 I tried to sync up my Yahoo mail account with Mac but I'm having trouble doing it. Gmail is fine, Yahoo ain't. I've resolved myself to this but once in a blue moon I like to try again. This time I am not able to delete the Yahoo mailbox and it's holding up my Gmail mail. It shows that the message is sending and stays that way. What did I do wrong!!!
