Conversion of a mailbox in the maildir format to the mbox format

Project description

Build Status


Convert mailbox from maildir format to mbox format, with support for nested folders

Improvements by Philippe Fremy:

  • porting to Python 3 to deal with filesystem encoding problems: works when moving maildir data from a partition supporting utf8 filenames (Ext3) to a partition supporting mbcs filenames (ntfs)
  • argument handling and help display
  • add support for nested directories
  • move to GitHub

To install:

  • either download directly the file and execute it:

     $ python --help
  • or install with pip, then run it with -m:

     $ pip install maildir2mbox
     $ python -m maildir2mbox --help
