I found the answer on the courier mailing list:
preauthtunnel = ssh -x -q imap 'IMAP_IDLE_TIMEOUT=20 IMAP_CAPABILITY="IMAP4rev1 UIDPLUS CHILDREN NAMESPACE SORT QUOTA IDLE" /usr/bin/imapd ./Maildir'

Why?

The problem is that courier imap does not read its configuration file
where I setup the IDLE configuration when you run it from the command line.

So you have to pass in the environment variables for IDLE and after that it works.

Hope this helps someone else.
