Fixed an security issue. For users in a network you can now prevent others to read the own .mailfilterrc by checking one box in the preferences (Thank's Maarten for this hint).
Implemented a search box. You can find it in the configurabe toolbar items.
Fixed some smaller memory leaks.
In the preferences is a new switch for the information window, whitch can now be shown at start-up.
A new tool is available: With the Shell script "mfreport" you can create HTML statistics about your applied filters from mailfilter.
