=head1 NAME
Mail::Box::IMAP4::Message - one message on a IMAP4 server
=head1 INHERITANCE
Mail::Box::IMAP4::Message
is a Mail::Box::Net::Message
is a Mail::Box::Message
is a Mail::Message
is a Mail::Reporter
=head1 SYNOPSIS
my $folder = new Mail::Box::IMAP4 ...
my $message = $folder->message(10);
=head1 DESCRIPTION
A C<Mail::Box::IMAP4::Message> represents one message on a IMAP4 server,
maintained by a L<Mail::Box::IMAP4|Mail::Box::IMAP4> folder. Each message is stored as
separate entity on the server, and maybe temporarily in your program
as well.

=item cache_head => BOOLEAN
=item cache_labels => BOOLEAN
All standard IMAP labels can be cached on the local server to improve
speed. This has the same dangers as setting C<write_labels> to false.
The caching starts when the first label of the message was read.

When a label is changed or its value read, using L<label()|Mail::Box::IMAP4::Message/"METHODS">, that info
should be sent to the IMAP server. But, this action could be superfluous,
for instance because the label was already set or clear, and communication
is expensive. On the other hand, someone else may use IMAP to make
changes in the same folder, and will get the updates too late or never...

The IMAP protocol defines its own names for the labels, which must
be set imediately to inform other IMAP clients which may have the
same folder open. But that can be changed with L<new(write_labels)|Mail::Box::IMAP4::Message/"METHODS">.
Some labels are translated to the corresponding IMAP system labels.

Get the names of all labels (LIST context, not efficient in IMAP4), or

=item $obj-E<gt>B<writeDelayed>(IMAP)
Write all delayed information, like label changes, to the server. This
is done under force, so should even be done for folders opened without
write-access. This method is called indirectly by a L<Mail::Box::write()|Mail::Box/"Internals">
or L<Mail::Box::close()|Mail::Box/"The folder">.
The IMAP argument is a Mail::IMAPClient which has the right folder
already selected.
Writing changes to the remote folder is not without hassle: IMAP4
(or is it only L<Mail::IMAPClient> doesn't support replacing header
or body. Therefore, when either of them change, the whole message is
rewritten to the server (which is supported), and the original flagged
for deletion.

See L<documentation in the base class|Mail::Box::Net::Message/"Status and X-Status fields">.
=head3 IMAP protocol flags
Labels (or flags) are known to all folder formats, but differ how they
are stored. Some folder types use message header lines to keep the
labels, other use a separate file. The IMAP protocol does not specify
how the labels are kept on the server, but does specify how they are named.
The label names as defined by the IMAP protocol are standardized into
the MailBox standard to hide folder differences. The following translations
are always performed:
\Seen => seen
\Answered => replied
\Flagged => flagged
\Deleted => deleted
\Draft => draft
\Recent => NOT old
=head3 Other labels
Of course, your program may be in need for more labels than those provided
by the protocol. You can still use these: they stay locally (and are
lost when the folder is closed). Some IMAP4 extensions permit more labels
than the basic RFC, but that is not yet supported by this implementation.
=head3 Caching labels
When you ask for one or more flags of a message more than once, you may
improve the overall performance by setting L<new(cache_labels)|Mail::Box::IMAP4::Message/"METHODS"> to C<YES>.
However, this may cause inconsistencies when multiple clients use the
same folder on the IMAP server.
You may also delay the label updates to the server until the
folder is closed (or for ever when read-only is required). When
L<Mail::Box::write()|Mail::Box/"Internals"> or L<Mail::Box::close()|Mail::Box/"The folder"> is called, it is decided
whether to throw all changes away or write after all.
=head1 DIAGNOSTICS
=over 4
=item Error: Cannot coerce a $class object into a $class object
=item Error: Cannot include forward source as $include.
Unknown alternative for the L<forward(include)|Mail::Message::Construct::Forward/"Constructing a message">. Valid choices are
C<NO>, C<INLINE>, C<ATTACH>, and C<ENCAPSULATE>.
=item Error: Cannot include reply source as $include.
Unknown alternative for the C<include> option of L<reply()|Mail::Message::Construct::Reply/"Constructing a message">. Valid
choices are C<NO>, C<INLINE>, and C<ATTACH>.
=item Error: Method bounce requires To, Cc, or Bcc
The message L<bounce()|Mail::Message::Construct::Bounce/"Constructing a message"> method forwards a received message off to someone
else without modification; you must specified it's new destination.
If you have the urge not to specify any destination, you probably
are looking for L<reply()|Mail::Message::Construct::Reply/"Constructing a message">. When you wish to modify the content, use
L<forward()|Mail::Message::Construct::Forward/"Constructing a message">.
=item Error: Method forwardAttach requires a preamble
=item Error: Method forwardEncapsulate requires a preamble
=item Error: No address to create forwarded to.
If a forward message is created, a destination address must be specified.
=item Error: No default mailer found to send message.
The message L<send()|Mail::Message/"The message"> mechanism had not enough information to automatically
find a mail transfer agent to sent this message. Specify a mailer
explicitly using the C<via> options.
=item Error: No rebuild rule $name defined.
=item Error: Only build() Mail::Message's; they are not in a folder yet
You may wish to construct a message to be stored in a some kind
of folder, but you need to do that in two steps. First, create a
normal L<Mail::Message|Mail::Message>, and then add it to the folder. During this
L<Mail::Box::addMessage()|Mail::Box/"The folder"> process, the message will get L<coerce()|Mail::Message/"Internals">-d
into the right message type, adding storage information and the like.
=item Error: Package $package does not implement $method.
Fatal error: the specific package (or one of its superclasses) does not
implement this method where it should. This message means that some other
related classes do implement this method however the class at hand does
not. Probably you should investigate this and probably inform the author
of the package.
=item Error: Unable to read delayed body.
=item Error: Unable to read delayed head.
=item Error: coercion starts with some object
