The folder list in the mail view lists all folder that can be used to sort mails into for temporary or final storage. You manage the folders in the settings section and freely choose the hierarchy of the folder tree.
Some of the folders have a special meaning and are used by the system to place messages in. These special folders are indicated with an individual icon in the list and usually cannot be deleted or renamed.
The assignment of special folders can be changed in Preferences > Special Folders.
Sorting messages to individual folders is as simple as that: drag a message from the list with the mouse and drop it onto the folder you want it to move to. That also works with multiple messages selected.
If the target folder is a subfolder and not currently visible, just hold the mouse over the parent folder while dragging and it’ll expand automatically after two seconds. Move the mouse (while dragging) over the folder list footer to let it scroll until the target folder moves into sight.
There’s also the possibility to copy a message into another folder instead of moving it there. Holding down the Shift key on the keyboard while dropping one or multiple messages on the destination folder will open a menu where you can choose to either Move or Copy them.
When reading a message in the fill message view screen, you’ll find a drop-down menu labelled Move to... in the toolbar on top. Select a folder from that menu and the message will be moved there. The message view screen will then load the next message in the list of the current folder.
If your webmail system has the Archive plugin installed, a button labelled Archive appears in the toolbar email task. This button moves the selected message(s) to the archive folder with one single click
You can configure how the archive folder is organized and divided into subfolders either by date, sender or originating folder.
In order to activate the archiving functions you first need to select a folder as archive in the Preferences > Special Folders settings.
The selected message(s) can be deleted from the current folder by clicking the Delete icon in the toolbar or by hitting the <Del> (or Backspace on Mac) key on your keybaord. This will by default move the message to the Trash folder and not delete it right away unless you do this for messages in the Trash folder. In order to delete the message in first place, hold down the Shift key on the keyboard while clicking the Delete button or when pressing <Del>.
There’s a preference in Settings > Preferences > Server Settings where the default behavior of message deletion can be changed.
