Currently, e-mail notification only works (and it is intended to work this way) for direct replies. We have, on our list of things to do for some future version, an idea to be able to "watch" a thread - so that you would be e-mailed every time someone posts to the thread.
The big problem with this or with multiple replies is that the time taken to actually post a message increases. The time taken to send one e-mail is quite low, but once you get into a large thread (say 20 or 30 posts deep) it can take quite a long time to send 20 or 30 e-mails for every new reply; this is the primary reason we haven't implemented it.
