mbox mail viewer

Hello:I need an mbox file viewer GUI program for openSUSE. A program I can use for opening mbox email files in a local directory. Thunderbird, Evolution, Clawsmail all can open/import mbox files, but they require setting up an email account which I don't want. I only want to open local mbox files and possibly manipulate them (view, save, copy to other folder). Pine/alpine can do this nicely, but it is a terminal program. I need something similar that is GUI and can show attached images.  Is there something like that for linux?Thanks in advance,Istvanps: I apologize if the message is garbled, it's the mail system I use.
