I would not call the table 'interim." That is a term that describes the function of the table. The table is for the many-to-many join. Many people can have many addresses. Yes, it's a table, not a derived table. It physically acts as the mapping point between a person and an address.

As to email vs. physical address, I would make two tables there. One for email. One for address. This also means two many-to-many/interim tables, one for each relationship back to the person. A person can have many email addresses.
