=head1 DIAGNOSTICS

=over 4

=item Warning: Cannot find head back for $uidl in $folder.

The header was read before, but now seems empty: the IMAP4 server does
not produce the header lines anymore.

=item Warning: Cannot read body for $uidl in $folder.

The header of the message was retrieved from the IMAP4 server, but the
body is not read, for an unknown reason.

=item Error: Copying failed for one message.

For some reason, for instance disc full, removed by external process, or
read-protection, it is impossible to copy one of the messages.  Copying will
proceed for the other messages.

=item Error: Couldn't select IMAP4 folder $name

=item Error: Destination folder $name is not writable.

The folder where the messages are copied to is not opened with write
access (see L<new(access)|Mail::Box/"Constructors">).  This has no relation with write permission
to the folder which is controlled by your operating system.

=item Warning: Different messages with id $msgid

The message id is discovered more than once within the same folder, but the
content of the message seems to be different.  This should not be possible:
each message must be unique.

=item Error: Folder $name not deleted: not writable.

The folder must be opened with write access via L<new(access)|Mail::Box/"Constructors">, otherwise
removing it will be refused.  So, you may have write-access according to
the operating system, but that will not automatically mean that this
C<delete> method permits you to.  The reverse remark is valid as well.

=item Notice: Impossible to keep deleted messages in IMAP

Some folder type have a 'deleted' flag which can be stored in the folder to
be performed later.  The folder keeps that knowledge even when the folder
is rewritten.  Well, IMAP4 cannot play that trick.

=item Error: Invalid timespan '$timespan' specified.

The string does not follow the strict rules of the time span syntax which
is permitted as parameter.

=item Warning: Message $uidl disappeared from $folder.

Trying to get the specific message from the server, but it appears to be
gone.

=item Warning: Message $uidl disappeared from $folder.

Trying to get the specific message from the server, but it appears to be
gone.

=item Warning: Message-id '$msgid' does not contain a domain.

According to the RFCs, message-ids need to contain a unique random part,
then an C<@>, and then a domain name.  This is made to avoid the creation
of two messages with the same id.  The warning emerges when the C<@> is
missing from the string.

=item Error: No IMAP4 transporter configured

=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 create subfolder $name of $folder.

The copy includes the subfolders, but for some reason it was not possible
to copy one of these.  Copying will proceed for all other sub-folders.
