NAME
       maildir2mbox - move mail from a maildir to an mbox


SYNOPSIS
       maildir2mbox


DESCRIPTION
       maildir2mbox moves mail from a maildir-format directory to an mbox-format file.

       You  must  supply three environment variables to maildir2mbox: MAILDIR is the name of your
       maildir directory; MAIL is the name of your mbox file; and MAILTMP  is  a  temporary  file
       that maildir2mbox can overwrite.  MAILTMP and MAIL must be on the same filesystem.

       maildir2mbox is reliable: it will not remove messages from MAILDIR until the messages have
       been successfully appended to MAIL.

       maildir2mbox locks MAIL to protect against simultaneous access by  a  mail  reader.   This
       locking  system  does not protect against simultaneous access by another maildir2mbox; you
       should run only one maildir2mbox at a time.
