Projects / isync


isync is a commandline application which synchronizes a local maildir-style mailbox with a remote IMAP4 mailbox, suitable for use in IMAP-disconnected mode. Multiple copies of the remote IMAP4 mailbox can be maintained, and all flags are synchronized. TLS/SSL is supported via imaps: or STARTTLS.

    Release Notes: This is a maintenance release.

    •  15 Sep 2004 17:35

      Release Notes: Essentially a rewrite: synchronization state storage concept, configuration, and the command line have changed entirely. A fully automated migration path is provided. The supported mailbox types can be freely paired. Message expunges are now propagated both ways, so there is no need for using mutt with maildir_trash any more. Additional trash options have been added. 'OneToOne' has been replaced with something more flexible. There is partial support for IMAP pipelining.

      •  07 Dec 2003 20:33

        Release Notes: This release has RSH/SSH tunnel support, PREAUTH support, suppression of superflous message up-/downloads on deletion and expunge and upload of locally generated messages, creation of missing remote mailboxes, and many fixes. There is a 'OneToOne' option to ignore any Mailbox specifications, and instead pick up all mailboxes from the local MailDir and remote Folder and map them 1:1 onto each other according to their names.

        •  20 Nov 2001 20:24

          Release Notes: A new commandline option to force creation of the local mailbox, a configuration option to mirror only the most recent messages from the IMAP server, and a few minor bugfixes.

          •  31 Oct 2001 09:13

            Release Notes: An option to synchronize all mailboxes specified in the configuration file was added, and many bugs were corrected.
