I did a search for this, but if someone knows of a thread that explain my specific issue please point me in the right direction. I've got my gmail account set up correctly, as per google's instructions, as IMAP in Apple Mail 4.4. When someone sends me a mail to my gmail account and I open it in Mail, it then doesn't show up in the inbox when I go to my gmail account online. There is no [IMAP] inbox shown in the sidebar in the online google account, even though it's checked (be default, and can't be unchecked) in the settings. If I happen to reply to such a mail via Apple Mail, I can fetch up the original mail that was sent to me online in the [IMAP] sent. But I thought IMAP meant that my inboxes for gmail via Apple Mail and gmail online should be identical?? Any help is greatly appreciated!
