means that modifications are immediately performed: there will be
a rename (move) from the old name to the new name. Labels may change
within in the message object as well.

time of receipt which may be seconds to hours off. But is still a good
guess... When the message header is not parsed, then this date is used.

=head1 DETAILS
=head2 Labels
=head3 Flags in filename
When new messages arrive on system and have to be stored in a maildir folder,
they are put in the C<new> sub-directory of the folder (first created in
the C<tmp> sub-directory and then immediately moved to C<new>).
The following information was found at L<http://cr.yp.to/proto/maildir.html>.
Each message is written in a separate file. The filename is
constructed from the time-of-arrival, a hostname, an unique component,
a syntax marker, and flags. For example C<1014220791.meteor.42:2,DF>.
The filename must match:
my ($time, $unique, $hostname, $info)
= $filename =~ m!^(\d+)\.(.*)\.(\w+)(\:.*)?$!;
my ($semantics, $flags)
= $info =~ m!([12])\,([DFPRST]*)$!;
my @flags = split //, $flags;
When an application opens the folder, there may be messages in C<new>
which are new arival, and messages in C<cur>. The latter are labeled
C<accepted>. To move a message from C<new> to C<cur>, you have two
options with the same effect:
$msg->accept;
$msg->label(accept => 1);
See L<accept()|Mail::Box::Maildir::Message/"Internals">, L<label()|Mail::Message/"Flags">, L<Mail::Box::Maildir::new(accept_new)|Mail::Box::Maildir/"METHODS">,
and L<Mail::Box::Maildir::acceptMessages()|Mail::Box::Maildir/"Internals">
The messages are moved, and their name is immediately
extended with flags. An example:
new/897979431.meteor.42 may become
cur/897979431.meteor.42:2,FS
The added characters C<':2,'> refer to the "second state of processing",
where the message has been inspected. And the characters (which should
be in alphabetic order) mean
D => draft
F => flagged
R => replied (answered)
S => seen
T => deleted (tagged for deletion)
Some maildir clients support
P => passed (resent/forwarded/bounced to someone else)
The flags will immediately change when L<label()|Mail::Message/"Flags"> or L<delete()|Mail::Message/"Flags"> is used,
which differs from other message implementations: maildir is stateless,
and should not break when applications crash.
=head1 DIAGNOSTICS
Error: Cannot coerce a $class object into a $class object
=over 4
=back
Error: Cannot create parser for $filename.
=over 4
For some reason (the previous message have told you already) it was not possible
to create a message parser for the specified filename.
=back
Error: Cannot include forward source as $include.
=over 4
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>.
=back
Error: Cannot include reply source as $include.
=over 4
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>.
=back
Error: Cannot write message to $filename: $!
=over 4
When a modified or new message is written to disk, it is first written
to a temporary file in the folder directory. For some reason, it is
impossible to create this file.
=back
Error: Failed to move $new to $filename: $!
=over 4
When a modified or new message is written to disk, it is first written
to a temporary file in the folder directory. Then, the new file is
moved to replace the existing file. Apparently, the latter fails.
=back
Error: Method bounce requires To, Cc, or Bcc
=over 4
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">.
=back
Error: Method forwardAttach requires a preamble
=over 4
=back
Error: Method forwardEncapsulate requires a preamble
=over 4
=back
Error: No address to create forwarded to.
=over 4
If a forward message is created, a destination address must be specified.
=back
Error: No default mailer found to send message.
=over 4
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.
=back
Error: No rebuild rule $name defined.
=over 4
=back
Error: Only build() Mail::Message's; they are not in a folder yet
=over 4
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.
=back
Error: Package $package does not implement $method.
=over 4
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.
=back
Error: Unable to read delayed body.
=over 4
For some reason, the header of the message could be read, but the body
cannot. Probably the file has disappeared or the permissions were
changed during the progress of the program.
=back
Error: Unable to read delayed head.
=over 4
Mail::Box tries to be I<lazy> with respect to parsing messages. When a
directory organized folder is opened, only the filenames of messages are
collected. At first use, the messages are read from their file. Apperently,
a message is used for the first time here, but has disappeared or is
unreadible for some other reason.
=back
Error: coercion starts with some object
