New messages, messagedeletions 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), sono identification conflicts can occur (unlike with some other mailsynchronizers).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; thischange 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* Help    Please see the man page for complete documentation.
