isync Documentation

Some Fossies usage hints in advance:

  1. To see the Doxygen generated documentation please click on one of the items in the steelblue colored "quick index" bar above or use the side panel at the left which displays a hierarchical tree-like index structure and is adjustable in width.
  2. If you want to search for something by keyword rather than browse for it you can use the client side search facility (using Javascript and DHTML) that provides live searching, i.e. the search results are presented and adapted as you type in the Search input field at the top right.
  3. Doxygen doesn't incorporate all member files but just a definable subset (basically the main project source code files that are written in a supported language). So to search and browse all member files you may visit the Fossies isync-1.4.1.tar.gz contents page and use the Fossies standard member browsing features (also with source code highlighting and additionally with optional code folding).

isync/mbsync - free (GPL) mailbox synchronization program http://isync.sf.net/

See AUTHORS for contact information.

mbsync'' is a command line application which synchronizes mailboxes; currently Maildir and IMAP4 mailboxes are supported. New messages, message deletions and flag changes can be propagated both ways. mbsync'' is suitable for use in IMAP-disconnected mode.

Synchronization is based on unique message identifiers (UIDs), so no identification conflicts can occur (unlike with some other mail synchronizers). Synchronization state is kept in one local text file per mailbox pair; these files are protected against concurrent mbsync'' processes. Mailboxes can be safely modified while mbsync'' operates. Multiple replicas of each mailbox can be maintained.

isync is the project name, while mbsync is the current executable name; this change was necessary because of massive changes in the user interface.

  • Features

    • Fine-grained selection of synchronization operations to perform
    • Synchronizes single mailboxes or entire mailbox collections
    • Partial mirrors possible: keep only the latest messages locally
    • Trash functionality: backup messages before removing them
    • IMAP features:
    • Supports TLS/SSL via imaps: (port 993) and STARTTLS
    • Supports SASL for authentication
    • Pipelining for maximum speed
  • Compatibility

    isync should work fairly well with any IMAP4 compliant server; servers that support the UIDPLUS and LITERAL+ extensions are most efficient.

    Courier 1.4.3 is known to be buggy, version 1.7.3 works fine.

    M$ Exchange (2013 at least) needs DisableExtension MOVE to be compatible with the Trash functionality.

  • Platforms

    At some point, ``isync'' has successfully run on: Linux, Solaris 2.7, OpenBSD 2.8, FreeBSD 4.3.

  • Requirements

    perl v5.14+ Berkeley DB 4.1+ (optional) OpenSSL for TLS/SSL support (optional) Cyrus SASL (optional) zlib (optional)

    The build from git also requires:

    GNU autotools (autoconf & automake) perl module Date::Parse (libtimedate-perl on Debian, perl-TimeDate on Fedora and Suse)

  • Installation

    ./autogen.sh (only when building from git) ./configure make sudo make install
