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

All standard IMAP labels can be cached on the local server to improve speed. This has the same
dangers as setting "write_labels" to false. The caching starts when the first label of the message
was read.

write_labels => BOOLEAN
When a label is changed or its value read, using label(), 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...

$obj->label($label|PAIRS)
With only one argument, the value related to $label is returned. With more that one argument, the
list is interpreted a label-value PAIRS to be set.
The IMAP protocol defines its own names for the labels, which must be set immediately to inform other
IMAP clients which may have the same folder open. But that can be changed with new(write_labels).
Some labels are translated to the corresponding IMAP system labels.
$obj->labels()
Get the names of all labels (LIST context, not efficient in IMAP4), or a reference to a hash with
labels. You should only use the returned hash to read the labels, because changes made to it will
not be passed to the remote server. See labels() to set values.

$obj->fetch( [$info, ...] )
Use the IMAP's "UID FETCH IMAP" command to get some data about this message. The $info request is
passed to Mail::Box::IMAP4::fetch(). Without $info, "ALL" information is retrieved and returned as a
HASH.

Inherited, see "Internals" in Mail::Message
$obj->writeDelayed($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
Mail::Box::write() or Mail::Box::close().
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 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.

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
. Example: of label translations
$imap->message(3)->label(replied => 1, draft => 0);
will result in a IMAP protocol statements like
A003 STORE 4 +FLAGS (\Answered)
A003 STORE 4 -FLAGS (\Draft)
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.
Caching labels
When you ask for one or more flags of a message more than once, you may improve the overall performance
by setting new(cache_labels) to "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 Mail::Box::write() or Mail::Box::close() is called, it is decided whether to throw
all changes away or write after all.
DIAGNOSTICS
Error: Cannot coerce a $class object into a $class object
Error: Cannot include forward source as $include.
Unknown alternative for the forward(include). Valid choices are "NO", "INLINE", "ATTACH", and
"ENCAPSULATE".
Error: Cannot include reply source as $include.
Unknown alternative for the "include" option of reply(). Valid choices are "NO", "INLINE", and
"ATTACH".
Error: Method bounce requires To, Cc, or Bcc
The message bounce() 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 reply(). When you wish to modify the content, use forward().
Error: Method forwardAttach requires a preamble
Error: Method forwardEncapsulate requires a preamble
Error: No address to create forwarded to.
If a forward message is created, a destination address must be specified.
Error: No default mailer found to send message.
The message send() mechanism had not enough information to automatically find a mail transfer agent
to sent this message. Specify a mailer explicitly using the "via" options.
Error: No rebuild rule $name defined.
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 Mail::Message, and then add it to the folder. During this
Mail::Box::addMessage() process, the message will get coerce()-d into the right message type, adding
storage information and the like.
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.
Error: Unable to read delayed body.
Error: Unable to read delayed head.
Error: coercion starts with some object
