Deleting mails in SPAM folder are not appearing in Trash-Folder

Hi Team,
if I delete a mail at the SPAM-folder, the mail is not moved to Trash-folder from my mail account. It is just gone away, without no chance to re-cap it.
Is there a configuration for that action possible, to move them to Trash-folder instead?
Cheers, Christoph

That is intentional. In a sense the Junk folder is a trash folder. Deleting a message in Junk irreversibly deletes it just like deleting a message in Trash. There is no secondary trash can for deleted trash/spam.
