archive-mail

Maintains maildir archives synced with current maildirs.

Motivation

I only store the last N messages in the maildir on my mail server, I
maintain a local archive which contains all mails I ever received. This
tool helps propagating new and modified messages from the maildir on my
server to my archive.

Usage

Sample usage for archiving the INBOX and GitHub maildir:

$ archive-mail mail/INBOX→/srv/nfs/archive/mail/INBOX \
    mail/GitHub→/srv/nfs/archive/mail/GitHub

This will propagate the following changes to the archive:

1. New messages from the current maildir, which were previously
   not tracked in the archive.
2. Changed flags, or file names in general, of messages already
   tracked in the maildir archive.
3. Location changes of messages in the archive. For example, messages
   moved between new/ and cur/ and messages moved between different
   maildirs. For example, between INBOX and GitHub in the example
   above.

The current maildir will never be modified. Messages deleted from the
current maildir will also not be deleted from the archive.
