On the Configuration Tab, you can customize POPFile and its look and feel:
Here, you can select a new skin that will change POPFile's appearance. Simply select a skin from the drop-down control and click the 'Apply' button.
The other control let's you choose a language for the POPFile UI. POPFile's supports many languages, but please note that not all the translations are complete.
These controls let you adjust the History Tab. You can select which columns should be displayed on the history page. You can choose from arrival time ('Arrived'), From, To, Cc, Subject, Date, Size, and Bucket.
You can also determine how many email should be listed per history page and how long messages should be kept in history before they are expired. Note that the messages will only be purged from POPFile's history, not from your mail client.
Should you find anything in the documentation that is incomplete, unclear, outdated or just plain wrong, please let us know and leave a note in the Documentation Forum.
