Now set up Apple Mail according the instructions in this post, using the three folders under the folder for Sent, Trash, and Junk. They should all have “Show in IMAP” checked you can remove any you don’t use (e.g. In the bottom you will see all your folders. In the top portion, uncheck all the “Show in IMAP” checkboxes except for Sent Mail, Spam, and Trash. Enable IMAP with the default options (auto-expunge on, do not limit the number of messages), and click Save Changes.
In Mail settings, click “Forwarding and POP/IMAP”.
Log on to your Gmail account (or Google Apps account, which I will refer to generically as Gmail from here on out).(I’ll cover the best way to do it on an iOS device in a future post.) You can set up your Apple Mail, iCal, and Address Book to automatically synchronize with a Gmail or Google Apps account.
