I'm not sure if I understand the question, but here's what I'm doing.
I did a test of "following" this thread (Replies to Posts). I clicked Notify, which will send an email to me when anyone posts in this particular thread.
When you no longer want to follow a particular thread, click the Unnotify button. This should stop the emails from the thread.
Click + button by Attachments and other options down below your post. If you want to be notified of replies, make sure that's checked. If not, clear that box.
Still testing...
