If I flag something as Spam it gets moved to the spam folder, but does the system automatically send any futures emails from that email address to the spam folder? If so where can I see a list of spam email addreses?
There is no list you can access to see what's on it. Spam filtering systems don't work like that. You just keep marking emails as spam when they get to your Inbox folder to help "train" the filters, and it can take time and a lot of markings to do that.
