where is my mail folder in time machine?
For the first time today I've backed up using Time Machine, on my MacBook Pro using OS 10.6.8.
When I check the external harddrive I've backed up to, I can see/discern all my MacBook Pro files except emails. Mail only appears in a folder called Applications as the application itself. A friend using Yosemite says within the Users folder he can drill down to a Mail folder that houses the emails. He also says he's never failed to get his emails back when he's restored from his Time Machine back-up. My Users folder does not have a Mail folder.
Can anyone reassure me that my emails are backed up somewhere, or direct me to where they are?
MacBook Pro, Mac OS X (10.6.8)
