Oswald Buddenhagen 0089f49c4a fix expiration when syncing only new messages
this was broken by commit de6dc699 - we now iterated only over far-side
messages, which we don't necessarily load, unlike the near-side ones
(which we need to do to know their current importance).

fix by iterating over sync entries instead of messages, which basically
restores the pre-19128f15 state in that regard. the minor catch here is
that we now need an auxiliary array to sort the sync entries by UIDs. on
the upside, we can also use it to avoid repeated calculation of the
flags.

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

* Help

    Please see the man page for complete documentation.
