I think it's been around for a long while... It's definitely in 7.1e.

Did you search using the web admin tool, that should find the setting 
for you, I think I've spelled it correctly...  Ahh, but I got the syntax 
wrong,
it's a boolean setting, so set it to 'true' then it subscribes all 
folders that exist.  which isn't quite the same thing but may be usable 
in your situation...

G_IMAP_AUTO_SUBSCRIBE "true"

Let me know if you still can't find it.
