You can do this by dragging the email(s) from the junk folder and dropping them in your Inbox. Note: Should you find something in your spam bucket which is legitimate (known as a false–positive), you can move emails from the spambucket/junk to your Inbox folder for normal mail retrieval to your email programme.
Select the spam bucket or junk folder on the left menu. Here you will find the spam messages caught by the spam filter.Now return to the Inbox by selecting the Mail icon at top right.This folder is created when the first spam mail is caught by the spam filter. If there is no spambucket or junk folder in the middle pane, it means that this mail account has never received any spam.
