usage: mh2maildir [options] old new [folder] transform mails stored in MH format into MAILDIR format using procmail(1) Options: -a Abort, if procmail produces differences in the MH and MAILDIR mail. Default: ask the user. (Some minor diff's, like removing a second From: line) are already ignored by default). -A Your DIFF program does not know the -a (Treat all files as text) flag. Default: it knows. The -a flag is needed in order to avoid false positive binary. -b char Replace a blank in a MH folder name by `char', default `_'. To remove all dots use `-b ""' -h Show help piped through more -H Show help. -d char Replace a dot in a MH folder name by `char', default `-'. To remove all dots use `-d ""' -D prog Use `prog' for presenting differences. Default: diff(1) if no DISPLAY variable is set, else a graphical diff-utility is searched. -f Force overwriting the `new' directory. Default: it should not exist and is created by mh2maildir. -kmail Create subdirectory names as used by kmail. Default: use same names as used by MH. This implies -R. -courier Create subdirectory names as used by courier-imap. Default: use same names as used by MH. This implies -R. -q Be quiet. -r Mark mails as read. Default: mails are marked as unread. -R Process recursively all subdirectories of `old'. For each subdirectory of `old' a subdirectory in `new' with the same name is created. Default: only the MH files contained in `old' are processed. -U Your DIFF program does not know the -u (Output NUM (default 3) lines of unified context) flag. DIFF is called with this flag only if differences between the original and the processed file are found and if you don't have the graphical diff-tools tkdiff, mgdiff or gvimdiff installed. -v Show version. Arguments: old The MH mail directory. new The MAILDIR mail directory. folder Store all mails below the `folder' of `new'. Default: store them direct below `new'. The integrity of the transformed mails is checked (using diff) The timestamp of the new mail file is set to old one. The MH mail files are not modified. Important Notes: It's also a good idea to shut down your incoming mail delivery while you're doing this, or else your new messages will get into whatever folder you happen to be converting at the moment. You should not chose `new' to be equal `old'. This is the initial release of mh2maildir, so if you encounter some problems or if you have ideas for extensions, please drop me an email. Example: Transform all mails below the directory Mail and its subdirectories and store them below the folder KMail/old. Mark all mails as read. mh2maildir -kmail -r -R Mail KMail old And the same thing to a courier-imap server mh2maildir -courier -r -R Mail EMAIL old From the KMAIL FAQ: Can I configure the location of my mail directory? Exit KMail, make a backup of ~/.kde/share/config/kmailrc, then open it with an editor and add e.g. folders=/home/username/.mail to the "[General]" section. Then move all your existing folders (including the hidden index files) to the new location. The next time you start KMail it will use /home/username/.mail instead of /home/username/Mail. Note that KMail will lose its filters if you change the mail directory's location but forget to move your existing folders.
