Which UML colors should this example be represented by?

Question

See UML colors here.

Here is the example, I have following entity classes:

User(name)

MailBox(owner: User, label)

Mail(from: User, to: User, subject, body, composeTime)

MailCopy(type, from: User, to: User, subject, body)

MailDelivery(mailCopy, mailBox)

Use case: Every users have three mailboxes by default: MailBox(*, draft), MailBox(*, received) and MailBox(*, sent). User(alice) composed a new Mail(alice, bob, hello, world), and clicked the "send" button. A new MailCopy(SOURCE, alice, bob, hello, world) is created and delivered to the MailBox(alice, sent), and another copy MailCopy(DEST, alice, bob, hello, world) is created and delivered to the MailBox(bob, received).

I want to know how to classify these entities according to the UML colors archetype?
