How big is my Optusnet Cable email mailbox?
Your mailbox can hold no more than 10 megabytes of emails and attachments at any one time. To be clear, your “mailbox” is where emails are stored before they are downloaded to your computer. Think of your “mailbox” as the letterbox outside your house. It might only hold a few hundred letters before it reaches capacity, but every time you go outside to check for new mail, you move the mail OUT of the letterbox and take it into your house. On the other hand, your “inbox” on your computer is practically unlimited (in the same way that the capacity of your house to store letters is practically unlimited).
