First you need to enable IMAP4 support on your GMail mailbox. To do this go to the GMail "Settings" page, then to the "Forwarding and POP/IMAP" tab.

There you can enable IMAP Access. If you can’t see these options, it might help to switch your mailbox language to English (US). (The option was missing in the Dutch version of GMail but appeared as soon as I selected English)
