- When trying to find unread messages
This option controls what happens if you press one of the shortcuts to go to the next or previous unread message (e.g. Space). If you ask KMail to go to the next unread message although there is no unread message below the currently selected message then the following happens:
If Do not Loop is selected then nothing will happen.
If Loop in Current Folder is selected then KMail will search from the beginning of the current folder for an unread message. If none is found then nothing happens.
If Loop in All Folders is selected then KMail will first search in the current folder for another unread message. If none is found then KMail will search the next folder containing unread messages.
Correspondingly, if you ask KMail to go to the previous unread message.
- When entering a folder
This option controls what happens if you open a folder.
If Jump to First Unread Message is selected then KMail will select the first message it finds that is marked as unread.
If Jump to Last Selected Message is selected then KMail will select the message that was selected when the folder was open the last time.
If Jump to Newest Message is selected then KMail will select the newest message by date.
If Jump to Oldest Message is selected then KMail will select the oldest message by date.
- Mark selected message as read after...
When you select a new or unread message, KMail will change the message's status to read after the number of seconds entered here. If you disable this option, messages will keep their new or unread status.
- Ask for action after dragging messages to another folder
When you drag a message to a different folder, a small popup will ask you if you want to move or copy the message. If you disable this option, the message will be moved immediately, without a popup.
- Open this folder on startup
Here you can set the folder that should be selected by default if you start KMail. If you use only IMAP folders then you might want to set this to your IMAP inbox folder. If you do that, you can collapse the local folders in the folder list, and then they will stay collapsed when KMail starts.

The trash folder is cleared of messages when you quit KMail if this option is selected.
