MBox viewer works perfect for archiving project IMAP folders as MBox-files. Missing a file open widget with input field of the path for copy-paste.
It's unpossible to open large MBOX files, it shows empty folder, no error message etc. It can not show correctly spec.characters (Czech), it can not to find Czech words in messages. There is not a possibility to sort messages (date, from...)
The product allows you to view and MBOX in a decently formatted fashion. The only suggestion would be to allow EXPORTS of Selected Email or ALL EMAIL to TXT or PRINT directly a particular Email. But in-lieu of importing into Thunderbird, this is a nice quick solution.. THANKS!
