Are email Subject lines encrypted when I am using SSL?

I recall hearing once that even with SSL on the Subject lines can be visible to an ISP. I use a Mac, OSX 10.6.x, and Mail, Outlook, Postbox, Zimbra, and Thunderbird. All have SSL checked in the preferences.
Am I mis-remembering that fact, or is it hidden/encrypted, just like the email body? Does it apply to emails I receive as well as send?
I did Google for over an hour but all the returns were for company- or service-specific setups, not a general email security answer.
