I have just set up a new Macbook Air, but Mail does not seem to have a 'trash' mailbox. I have deleted some messages, but they have disappeared totally.
Mail > Preferences > Accounts > Mailbox Behaviors
What do you have under "Trash" there?
I have 'move deleted messages to the trash mailbox'. However, the trash mailbox has 'miraculously' appeared.
Thanks for your help, though.
