I want to know more information/stats about the JunkMail folder and the messages it can support?
You may set the length of time the messages remain in the JunkMail folder on the Settings/Accounts page when you log in to your 0Spam.com account. It is located near the top of the page where it says “Allow senders X days to confirm their message before it is deleted from the server.” Your JunkMail folder can currently support a virtually unlimited number of messages and the total size is also virtually unlimited. The JunkMail folder does not support mails over 250 Kb in size. So, if you receive an E-mail that is larger than this size, which will probably have an attachment, it will not be marked as spam. We change the 250 Kb size from time to time.
