Mail: keyboard shortcut to move email to trash? I'm on macOS Mojave, Mail is version 12.4.

Problem

I've just realized that cmd + delete is deleting (ie irretrievably removing from my machine and server) my emails instead of moving them to the trash. I want my emails to go to the trash so I can recover them later if needed. I would like to change the behavior of that keyboard shortcut, but I doubt that's possible on macOS so I'd settle for adding a new shortcut. However, I can't figure out how to do that.

What I've tried

I've tried changing the mailbox behavior, which is what others have suggested, but there doesn't seem to be an option (see screenshot below). I'm using MailFence if that's important.



I've tried adding a keyboard shortcut specific to Mail (see screenshot below), but it isn't doing what I want. Note that I have tried to name the shortcut 'Move to Trash', 'Move to trash', and 'Move to Trash Foo' where 'Foo' is the mailbox description and when I use the menu to move a message into trash I select Message -> Move to -> Trash -> Foo
Actually, you don't need to go to all this effort. The default command+delete keyboard shortcut will do exactly what you want, so long as you've set your Mail preferences that way.

In summary, you need to:


Go to Mail > Preferences
Select the Accounts tab
Select the account (or email address) from the left pane
In the right pane, select the Mailbox Behaviours tab
At the bottom, tick the checkbox for Move deleted messages to the Bin mailbox
While at it, ensure that the other settings on this tab for erasing deleted messages are what you want


Now when using the command+delete keyboard shortcut to delete emails they will be moved to the Bin mailbox for the Account in question.
