NAME
mb2md — Converts Mbox mailboxes to Maildir format.
SYNOPSIS
mb2md [-h]
mb2md [-c] [-m] [-d destdir]
mb2md [-c] [-s sourcefile] [-d destdir]
mb2md [-c] [-s sourcedir] [-l wu-mailboxlist] [-R|-f somefolder] [-d destdir] [-r strip_extension]
DESCRIPTION
mb2md Converts Mbox mailboxes to Maildir format.
OPTIONS
-h Show summary of options.
-c Use the Content-Length: headers (if present) to find the beginning of the next message. Use
with caution! Results may be unreliable. I recommend to do a run without "-c" first and only
use it if you are certain, that the mbox in question really needs the "-c" option.
-m If this is used then the source will be the single mailbox at /var/spool/mail/blah for user
blah and the destination mailbox will be the "destdir" mailbox itself.
-s sourcedir
Directory, relative to the user's home directory, which is where the the "somefolders"
directories are located. Or if directory starts with a "/" or "." it is taken as a absolute
path, e.g. /mnt/oldmail/user _OR_ A single mbox file which will be converted to the destdir.
-R If defined, do not skip directories found in a mailbox directory, but runs recursively into
each of them, creating all wanted folders in Maildir.
Incompatible with '-f'
-f somefolder
Directories, relative to "sourcedir" where the Mbox files are. All mailboxes in the "sourcedir"
directory will be converted and placed in the "destdir" directory. (Typically the Inbox
directory which in this instance is also functioning as a folder for other mailboxes.)
The "somefolder" directory name will be encoded into the new mailboxes' names. See the example
in the USAGE file (see below).
This does not save an UW IMAP dummy message file at the start of the Mbox file. Small changes
in the code could adapt it for looking for other distinctive patterns of dummy messages too.
Don't let the source directory you give as "somefolders" contain any "."s in its name, unless
you want to create subfolders from the IMAP user's point of view. See the example in the USAGE
file (see below).
Incompatible with '-R'
-d destdir
Directory where the Maildir format directories will be created. If not given, then the
destination will be ~/Maildir . Typically, this is what the IMAP server sees as the Inbox and
the folder for all user mailboxes. If this begins with a '/' the path is considered to be
absolute, otherwise it is relative to the users home directory.
-r strip_extension
If defined this extension will be stripped from the original mailbox file name before creating
the corresponding maildir. The extension must be given without the leading dot ("."). See the
example in the USAGE file (see below).
-l WU-file
File containing the list of subscribed folders. If migrating from WU-IMAP the list of
subscribed folders will be found in the file called .mailboxlist in the users home directory.
This will convert all subscribed folders for a single user:
/bin/mb2md -s mail -l .mailboxlist -R -d Maildir
and for all users in a directory as root you can do the following:
for i in *; do echo $i;su - $i -c "/bin/mb2md -s mail -l .mailboxlist -R -d Maildir";done
USAGE
Please read the USAGE documentation (zless /usr/share/doc/mb2md/USAGE.gz).
