* Command line maintenance tool for MailSite's on-disk
* (FileMailStorage) mail tree. Subcommands:
*
* import <maildir_or_mbox_path> <user> <folder>
* Import a source into a MailSite folder, preserving IMAP
* flags and internal dates, with a copied/skipped tally. A
* directory is read as a dovecot Maildir folder (its cur/ and
* new/ subdirectories); a file is read as an mbox and split
* on its "From " postmark lines. Streams the source so large
* sources stay within a flat memory budget, and is resumable
* and idempotent via a per-folder import journal, so a re-run
* or an interrupted run does not duplicate messages.
*
* export <user> <folder> <out_file>
* Export a user's local mail folder to an mbox file at
* out_file. Each message is written with a "From " postmark
* dated from its IMAP internal date, Status and X-Status
* headers carrying its stored flags so a later import
* recovers them, and ">From " quoting of body lines that
* begin with "From ". Streams the folder a message at a time
* so a large folder stays within a flat memory budget. The
* output file is overwritten if it already exists.
*
* verify <user>
* Print the message count of every folder for a user.
*
* Run only while MailServer is stopped: import allocates UIDs,
* which conflicts with a live daemon writing the same tree.
*
* Usage (from src/executables):
* php MailTool.php import <maildir_or_mbox_path> <user> <folder>
* php MailTool.php export <user> <folder> <out_file>
* php MailTool.php verify <user>
