When all emails have been loaded, you can delete one or more emails directly from the server. Select the emails, which you want to delete, in the main window's listview and press the Del keyboard button or choose the menu command File | Delete.

A message box appears, asking if you really want to delete the selected emails:

Confirm this security query by cklicking Yes or pressing the Enter keyboard button. Afterwards PopMan connects to the POP3 server containing the emails and deletes them.

Warning: The deletion of emails is permanent and irreversible!
