=head1 DESCRIPTION

A C<Mail::Box::Dir::Message> is a base class for one message in a
directory organized folder; each message is stored in a separate file.
There are no objects of type C<Mail::Box::Dir::Message>, only extensions
are allowed to be created.

At the moment, two of these extended message types are implemented:

=over 4

=item * L<Mail::Box::MH::Message|Mail::Box::MH::Message>

which represents one message in a L<Mail::Box::MH|Mail::Box::MH> folder.

=item * L<Mail::Box::Maildir::Message|Mail::Box::Maildir::Message>

which represents one message in a L<Mail::Box::Maildir|Mail::Box::Maildir> folder.

=head1 DIAGNOSTICS

I<Error:> Cannot create parser for $filename.

For some reason (the previous message have told you already) it was not possible
to create a message parser for the specified filename.

I<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>.

I<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>.

I<Error:> Cannot write message to $filename: $!

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.

I<Error:> Failed to move $new to $filename: $!

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.

I<Error:> No address to create forwarded to.

If a forward message is created, a destination address must be specified.

I<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.

I<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.

I<Error:> Unable to read delayed body.

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.

I<Error:> Unable to read delayed head.

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.

I<Error:> forwardAttach requires a preamble object


I<Error:> forwardEncapsulate requires a preamble object


I<Error:> no rebuild rule $name defined.
