Since I moved to a new hosting company I started using IMAP email accounts, and Mail is constantly showing connection problems (red light in Connection Doctor) even though it can send and receive emails successfully. I have allocated each mailbox on the server to things like 'use this mailbox for trash' but the problems continue. How do I find out more specifically what the problem is - unfortunately I don't recognise any obvious problems from the 'show detail' panel.
My MobileMe account and my POP account with my ISP are both working fine and show a green light.
