DESCRIPTION

A Mail::Box::Manager creates Mail::Box objects. But you already knew, because you started with the Mail::Box-Overview manual page. That page is obligatory reading, sorry!

Mail::Box is the base class for accessing various types of mailboxes (folders) in a uniform manner. The various folder types vary on how they store their messages, but when some effort those differences could be hidden behind a general API. For example, some folders store many messages in one single file, where other store each message in a separate file withing the same directory.

No object in your program will be of type Mail::Box: it is only used as base class for the real folder types. Mail::Box is extended by

  • Mail::Box::Mbox

    a folder type in which all related messages are stored in one file. This is very common folder type for UNIX.

  • Mail::Box::MH

    this folder creates a directory for each folder, and a message is one file inside that directory. The message files are numbered sequentially on order of arrival. A special .mh_sequences file maintains flags about the messages.

  • Mail::Box::Maildir

    maildir folders have a directory for each folder, although the first implementation only supported one folder in total. A folder directory contains a tmp, new, and cur subdirectory, each containting messages with a different purpose. New messages are created in tmp, then moved to new (ready to be accepted). Later, they are moved to the cur directory (accepted). Each message is one file with a name starting with timestamp. The name also contains flags about the status of the message.

  • Mail::Box::POP3

    Pop3 is a protocol which can be used to retreive messages from a remote system. After the connection to a POP server is made, the messages can be looked at and removed as if they are on the local system. [IMPLEMENTATION NOT FINISHED YET]

Other folder types are on the (long) wishlist to get implemented. Please, help implementing more of them.

METHODS

Initiation

new OPTIONS

(Class method) Open a new folder. A list of labeled OPTIONS for the mailbox can be supplied. Some options pertain to Mail::Box, and others are added by sub-classes. The list below describes all the options provided by any Mail::Box.

To control delay-loading of messages, as well the headers as the bodies, a set of *_type options are available. extract determines whether we want delay-loading.

 OPTION               DEFAULT
 access               'r'
 body_delayed_type    'Mail::Message::Body::Delayed'
 body_type            <folder specific>
 coerce_options       []
 create               <false>
 extract              10240
 field_type           undef
 folder               $ENV{MAIL}
 folderdir            undef
 head_delayed_type    'Mail::Message::Head::Delayed'
 head_type            'Mail::Message::Head::Complete'
 keep_dups            <false>
 lock_file            undef
 lock_timeout         1 hour
 lock_type            'Mail::Box::Locker::DotLock'
 lock_wait            10 seconds
 locker               undef
 log                  'WARNINGS'
 manager              undef
 message_type         'Mail::Box::Message'
 multipart_type       'Mail::Message::Body::Multipart'
 remove_when_empty    <true>
 save_on_exit         <true>
 trace                'WARNINGS'
 trusted              <depends on folder location>
access => MODE

Access-rights to the folder. MODE can be read-only ("r"), append ("a"), and read-write ("rw"). Folders are opened for read-only ("r") (which means write-protected) by default!

These MODEs have no relation to the modes actually used to open the folder files within this module. For instance, if you specify "rw", and open the folder, only read permission on the folder-file is required.

Be warned: writing a MBOX folder may create a new file to replace the old folder. The permissions and owner of the file get changed by this.

body_delayed_type => CLASS

The bodies which are delayed: which will be read from file when it is needed, but not before.

body_type => CLASS|CODE

When messages are read from a folder-file, the headers will be stored in a head_type object. For the body, however, there is a range of choices about type, which are all described in the Mail::Message::Body manual page.

Specify a CODE-reference which produces the body-type to be created, or a CLASS of the body which is used when the body is not a multipart or nested. In case of a code reference, the header structure is passed as first argument to the routine.

Do not return a delayed body-type (like ::Delayed), because that is determined by the extract option while the folder is opened. Even delayed message will require some real body type when they get parsed eventually. Multiparts and nested messages are also outside your control.

For instance:

 $mgr->open('InBox', body_type => \&which_body);

 sub which_body($) {
     my $head = shift;
     my $size = $head->guessBodySize || 0;
     my $type = $size > 100000 ? 'File' : 'Lines';
     "Mail::Message::Body::$type";
 }

The default depends on the mail-folder type, although the general default is Mail::Message::Body::Lines. Please check the applicable manual pages.

coerce_options => ARRAY

Keep configuration information for messages which are coerced into the specified folder type, starting with a different folder type (or even no folder at all). Messages which are coerced are always fully read, so this kind of information does not need to be kept here.

create => BOOLEAN

Automatically create the folder when it does not exist yet. This will only work when access is granted for writing or appending to the folder.

Be careful: you may create a different folder type than you expect unless you explicitly specify the type (See Mail::Box::Manager::open(type)).

extract => INTEGER | CODE | METHOD | 'LAZY'|'ALWAYS'

Defines when to parse (process) the content of the message. When the header of a message is read, you may want to postpone the reading of the body: header information is more often needed than the body data, so why parse it always together? The cost of delaying is not too high, and with some luck you may never need parsing the body.

If you supply an INTEGER to this option, bodies of those messages with a total size less than that number will be extracted from the folder only when necessary. Messages where the size (in the Content-Length field) is not included in the header, like often the case for multiparts and nested messages, will not be extracted by default.

If you supply a CODE reference, that subroutine is called every time that the extraction mechanism wants to determine whether to parse the body or not. The subroutine is called with the following arguments:

 CODE->(FOLDER, HEAD)

where FOLDER is a reference to the folder we are reading. HEAD refers to the Mail::Message::Head::Complete head of the message at hand. The routine must return a true value (extract now) or a false value (be lazy, do not parse yet). Think about using the Mail::Message::guessBodySize() and Mail::Message::guessTimestamp() on the header to determine your choice.

The third possibility is to specify the NAME of a method. In that case, for each message is called:

 FOLDER->NAME(HEAD)

Where each component has the same meaning as described above.

The fourth way to use this option involves constants: with 'LAZY' all messages will be delayed. With 'ALWAYS' you enforce unconditional parsing, no delaying will take place. The latter is usuful when you are sure you always need all the messages in the folder.

 $folder->new(extract => 'LAZY');  # Very lazy
 $folder->new(extract => 10000);   # Less than 10kB

 # same, but implemented yourself
 $folder->new(extract => &large);
 sub large($) {
    my ($f, $head) = @_;
    my $size = $head->guessBodySize;
    defined $size ? $size < 10000 : 1
 };

 # method call by name, useful for Mail::Box extensions
 # The example selects all messages sent by you to be loaded
 # without delay.  Other messages will be delayed.
 $folder->new(extract => 'sent_by_me');
 sub Mail::Box::send_by_me($) {
     my ($self, $header) = @_;
     $header->get('from') =~ m/\bmy\@example.com\b/i;
 }
field_type => CLASS

The type of the fields to be used in a header. Must extend Mail::Message::Field.

folder => FOLDERNAME

Which folder to open (for reading or writing). When used for reading (the access option set to "r" or "a") the mailbox should already exist and must be readable. The file or directory of the mailbox need not exist if it is opened for reading and writing ("rw"). Write-permission is checked when opening an existing mailbox.

folderdir => DIRECTORY

Where are folders to be found by default? A folder-name may be preceded by a equals-sign (=, a mutt convension) to explicitly state that the folder is located below the default directory. For example: in case folderdir => '/tmp' and folder => '=abc', the name of the folder-file is '/tmp/abc'. Each folder type has already some default set.

head_delayed_type => CLASS

The headers which are delayed: which will be read from file when it is needed, but not before.

head_type => CLASS

The type of header which contains all header information. Must extend Mail::Message::Head::Complete.

keep_dups => BOOLEAN

Indicates whether or not duplicate messages within the folder should be retained. A message is considered to be a duplicate if its message-id is the same as a previously parsed message within the same folder. If this option is false (the default) such messages are automatically deleted, because it is considered useless to store the same message twice.

lock_file => FILENAME

The name of the file which is used to lock. This must be specified when locking is to be used.

lock_timeout => SECONDS

When the lock file is older than the specified number of SECONDS, it is considered a mistake. The original lock is released, and accepted for this folder.

lock_type => CLASS|STRING

The type of the locker object. This may be the full name of a CLASS which extends Mail::Box::Locker, or one of the known locker types 'DotLock', 'File', 'MULTI', 'NFS', 'POSIX', or 'NONE'.

lock_wait => SECONDS

SECONDS to wait before failing on opening this folder.

locker => OBJECT

An OBJECT which extends Mail::Box::Locker, and will handle folder locking replacing the default lock behavior.

log => LEVEL

See Mail::Reporter::new(log)

manager => MANAGER

A reference to the object which manages this folder -- typically an Mail::Box::Manager instance.

message_type => CLASS

What kind of message-objects are stored in this type of folder. The default is Mail::Box::Message (which is a sub-class of Mail::Message). The class you offer must be an extension of Mail::Box::Message.

multipart_type => CLASS

The default type of objects which are to be created for multipart message bodies.

remove_when_empty => BOOLEAN

Determines whether to remove the folder file or directory automatically when the write would result in a folder without messages nor sub-folders.

save_on_exit => BOOLEAN

Sets the policy for saving the folder when it is closed. A folder can be closed manually (see close()) or in a number of implicit ways, including on the moment the program is terminated.

trace => LEVEL

See Mail::Reporter::new(trace)

trusted => BOOLEAN

Flags whether to trust the data in the folder or not. Folders which reside in your folderdir will be trusted by default (even when the names if not specified staring with =). Folders which are outside the folderdir or read from STDIN (Mail::Message::Construct::read()) are not trused by default, and require some extra checking.

If you do not check encodings of received messages, you may print binary data to the screen, which is a security risk.

Opening folders

clone OPTIONS

Create a new folder, with the same settings as this folder. One of the specified options must be new folder to be opened. Other options overrule those of the folder where this is a clone from.

Examples:

 my $folder2 = $folder->clone(folder => '=jan');
create FOLDERNAME, OPTIONS

(Class method) Create a folder. If the folder already exists, it will be left unchanged. As options, you may specify:

 OPTION               DEFAULT
 folderdir            undef
folderdir => DIRECTORY

When the foldername is preceded by a =, the folderdir directory will be searched for the named folder.

folderdir [DIRECTORY]

Get or set the DIRECTORY which is used to store mail-folders by default.

Examples:

 print $folder->folderdir;
 $folder->folderdir("$ENV{HOME}/nsmail");
foundIn [FOLDERNAME], OPTIONS

(class method) Determine if the specified folder is of the type handled by the folder class. This method is extended by each folder sub-type.

The FOLDERNAME specifies the name of the folder, as is specified by the application. You need to specified the folder option when you skip this first argument.

OPTIONS is a list of extra information for the request. Read the documentation for each type of folder for folder-specific options, but each folder class will at least support the folderdir option:

 OPTION               DEFAULT
 folderdir            undef
folderdir => DIRECTORY

The location where the folders of this class are stored by default. If the user specifies a name starting with a =, that indicates that the folder is to be found in this default DIRECTORY.

Examples:

 Mail::Box::Mbox->foundIn('=markov', folderdir => "$ENV{HOME}/Mail");
 Mail::Box::MH->foundIn(folder => '=markov');

On open folders

addMessage MESSAGE
addMessages MESSAGE [, MESSAGE, ...]

Add a message to the folder. A message is usually a Mail::Box::Message object or a sub-class thereof. The message shall not be in an other folder, when you use this method. In case it is, use moveMessage() or copyMessage() via the manager.

Messages with id's which already exist in this folder are not added.

Examples:

 $folder->addMessage($msg);
 $folder->addMessages($msg1, $msg2, ...);
copyTo FOLDER, OPTIONS

Copy the folder's messages to a new folder. The new folder may be of a different type.

 OPTION               DEFAULT
 delete_copied        <false>
 select               'ACTIVE'
 subfolders           <folder type dependent>
delete_copied => BOOLEAN

Flag the messages from the source folder to be deleted, just after it was copied. The deletion will only take effect when the originating folder is closed.

select => 'ACTIVE'|'DELETED'|'ALL'|LABEL|!LABEL|FILTER

Which messages are to be copied. See messages(description) about how this works.

subfolders => BOOLEAN|'FLATTEN'|'RECURSE'

How to handle sub-folders. When false (0 or undef), sub-folders are simply ignored. With 'FLATTEN', messages from sub-folders are included in the main copy. 'RECURSE' recursively copies the sub-folders as well. By default, when the destination folder supports sub-folders 'RECURSE' is used, otherwise 'FLATTEN'. A value of true will select the default.

Examples:

 my $mgr  = Mail::Box::Manager->new;
 my $imap = $mgr->open(type => 'imap', host => ...);
 my $mh   = $mgr->open(type => 'mh', folder => '/tmp/mh',
     create => 1, access => 'w');

 $imap->copyTo($mh, delete_copied => 1);
 $mh->close; $imap->close;
modified [BOOLEAN]

modified checks if the folder is modified, optionally after setting the flag. A folder is modified when any of the messages is to be deleted, any of the messages has changed, or messages are added after the folder was read from file.

name

Returns the name of the folder. What the name represents depends on the actual type of mailbox used.

Examples:

 print $folder->name;
organization

Returns how the folder is organized: as one 'FILE' with many messages, a 'DIRECTORY' with one message per file, or by a 'REMOTE' server.

update OPTIONS

Read new messages from the folder, which where received after opening it. This is quite dangerous and shouldn't be possible: folders which are open are locked. However, some applications do not use locks or the wrong kind of locks. This method reads the changes (not always failsafe) and incorporates them in the open folder administration.

The OPTIONS are extra values which are passed to the updateMessages() method which is doing the actual work here.

writable

Checks whether the current folder is writable.

Examples:

 $folder->addMessage($msg) if $folder->writable;

Closing the folder

DESTROY

This method is called by Perl when an folder-object is no longer accessible by the rest of the program.

close OPTIONS

lose the folder, optionally writing it. close takes the same options as write(), as well as a few others:

WARNING: When moving messages from one folder to another, be sure to write the destination folder before writing and closing the source folder. Otherwise you may lose data if the system crashes or if there are software problems.

 OPTION               DEFAULT
 force                <false>
 write                'MODIFIED'
force => BOOLEAN

Override the access setting specified when the folder was opened. This option only has an effect if its value is TRUE. NOTE: Writing to the folder may not be permitted by the operating system, in which case even force will not help.

write => 'ALWAYS'|'NEVER'|'MODIFIED'

Specifies whether the folder should be written. As could be expected, 'ALWAYS' means always (even if there are no changes), 'NEVER' means that changes to the folder will be lost, and 'MODIFIED' only saves the folder if there are any changes.

delete

Remove the specified folder file or folder directory (depending on the type of folder) from disk. Of course, THIS IS DANGEROUS: you "may" lose data.

WARNING: When moving messages from one folder to another, be sure to write the destination folder before deleting the source folder. Otherwise you may lose data if the system crashes or if there are software problems.

Examples:

 my $folder = Mail::Box::Mbox->new(folder => 'InBox');
 $folder->delete;

The messages

current [NUMBER|MESSAGE|MESSAGE-ID]

Some mail-readers keep the current message, which represents the last used message. This method returns [after setting] the current message. You may specify a NUMBER, to specify that that message number is to be selected as current, or a MESSAGE/MESSAGE-ID (as long as you are sure that the header is already loaded, otherwise they are not recognized).

Examples:

 $folder->current(0);
 $folder->current($message);
find MESSAGE-ID

Like messageId(), this method searches for a message with the MESSAGE-ID, returning the corresponding message object. However, find will cause unparsed message in the folder to be parsed until the message-id is found. The folder will be scanned back to front.

message INDEX [,MESSAGE]

Get or set a message with on a certain index. Messages which are flagged for deletion are counted. Negative indexes start at the end of the folder.

Examples:

 my $msg = $folder->message(3);
 $folder->message(3)->delete;   # status changes to `deleted'
 $folder->message(3, $msg);
 print $folder->message(-1);    # last message.
messageId MESSAGE-ID [,MESSAGE]

With one argument, returns the message in the folder with the specified MESSAGE-ID. If a reference to a message object is passed as the optional second argument, the message is first stored in the folder, replacing any existing message whose message ID is MESSAGE-ID. (The message ID of MESSAGE need not match MESSAGE-ID.)

The MESSAGE-ID may still be in angles, which will be stripped. In that case blanks (which origin from header line folding) are removed too. Other info around the angles will be removed too.

WARNING: when the message headers are delay-parsed, the message might be in the folder but not yet parsed into memory. In this case, use the find() method instead of messageId if you really need a thorough search.

Examples:

 my $msg = $folder->messageId('<complex-message.id>');
 $folder->messageId("<complex-message\n.id>", $msg);
 my $msg = $folder->messageId('complex-message.id');
 my $msg = $folder->messageId('garbage <complex-message.id> trash');
messageIds

Returns a list of all message-ids in the folder, including those of messages which are to be deleted.

For some folder-types (like MH), this method may cause all message-files to be read. See their respective manual pages.

Examples:

 foreach my $id ($folder->messageIds) {
    $folder->messageId($id)->print;
 }
messages ['ALL',RANGE,'ACTIVE','DELETED',LABEL,!LABEL,FILTER]

Returns multiple messages from the folder. The default is 'ALL' which will return (as expected maybe) all the messages in the folder. The 'ACTIVE' flag will return the messages not flagged for deletion. This is the opposite of 'DELETED', which returns all messages from the folder which will be deleted when the folder is closed.

You may also specify a RANGE: two numbers specifying begin and end index in the array of messages. Negative indexes count from the end of the folder. When an index is out-of-range, the returned list will be shorter without complaints.

Everything else than the predefined names is seen as labels. The messages which have that label set will be returned. When the sequence starts with an exclamation mark (!), the search result is reversed.

For more complex searches, you can specify a FILTER, which is simply a code reference. The message is passed as only argument.

Examples:

 foreach my $message ($folder->messages) {...}
 foreach my $message (@$folder) {...}
 my @messages   = $folder->messages;
 my @messages   = $folder->messages('ALL');    # same

 my $subset     = $folder->messages(10,-8);

 my @not_deleted= grep {not $_->deleted} $folder->messages;
 my @not_deleted= $folder->messages('ACTIVE'); # same

 my $nr_of_msgs = $folder->messages;           # scalar context
 $folder->[2];                  # third message, via overloading

 $mgr->moveMessages($spamfolder, $inbox->message('spam'));
 $mgr->moveMessages($archive, $inbox->message('seen'));
scanForMessages MESSAGE, MESSAGE-IDS, TIMESTAMP, WINDOW

The MESSAGE which is known contains references to messages before it which are not found yet. But those messages can be in the same folder. Scan back in this folder for the MESSAGE-IDS (which may be one string or a reference to an array of strings). The TIMESTAMP and WINDOW (see options in new()) limit the search.

Sub-folders

listSubFolders OPTIONS

(Class and Instance method) List the names of all sub-folders to this folder. Use these names in openSubFolder(), to open these folders on a mailbox type way. For Mbox-folders, sub-folders are simulated.

 OPTION               DEFAULT
 check                <false>
 folder               <obligatory>
 folderdir            <from folder>
 skip_empty           <false>
check => BOOLEAN

Specifies whether empty folders (folders which currently do not contain any messages) should be included. It may not be useful to open empty folders, but saving to them is useful.

folder => FOLDERNAME

The folder whose sub-folders should be listed.

folderdir => DIRECTORY
skip_empty => BOOL

Shall empty folders (folders which currently do not contain any messages) be included? Empty folders are not useful to open, but may be useful to save to.

Examples:

 my $folder = $mgr->open('=in/new');
 my @subs = $folder->listSubFolders;

 my @subs = Mail::Box::Mbox->listSubFolders(folder => '=in/new');
 my @subs = Mail::Box::Mbox->listSubFolders; # toplevel folders.
openRelatedFolder OPTIONS

Open a folder (usually a sub-folder) with the same options as this one. If there is a folder manager in use, it will be informed about this new folder. OPTIONS overrule the options which where used for the folder this method is called upon.

openSubFolder NAME, OPTIONS

Open (or create, if it does not exist yet) a new subfolder in an existing folder.

Examples:

 my $folder = Mail::Box::Mbox->new(folder => '=Inbox');
 my $sub    = $folder->openSubFolder('read');

Message threads [internals]

toBeThreaded MESSAGES
toBeUnthreaded MESSAGES

The specified message is ready to be included in (or remove from) a thread. This will be passed on to the mail-manager, which keeps an overview on which thread-detection objects are floating around.

Reading and Writing [internals]

appendMessages OPTIONS

(Class method) Append one or more messages to an unopened folder. Usually, this method is called by the Mail::Box::Manager (its method appendMessage()), in which case the correctness of the folder type is checked.

This method takes a list of labeled parameters, which may contain any option which can be used when a folder is opened (most importantly folderdir).

 OPTION               DEFAULT
 folder               <obligatory>
 message              undef
 messages             undef
folder => FOLDERNAME

The name of the folder to which the messages are to be appended. The folder implementation will avoid opening the folder when possible, because this is resource consuming.

message => MESSAGE
messages => ARRAY-OF-MESSAGES

One reference to a MESSAGE or a reference to an ARRAY of MESSAGEs, which may be of any type. The messages will be first coerced into the correct message type to fit in the folder, and then will be added to it.

Examples:

 my $message = Mail::Message->new(...);
 Mail::Box::Mbox->appendMessages
  ( folder    => '=xyz'
  , message   => $message
  , folderdir => $ENV{FOLDERS}
  );

better:

 my Mail::Box::Manager $mgr;
 $mgr->appendMessages($message, folder => '=xyz');
coerce MESSAGE

Coerce the MESSAGE to be of the correct type to be placed in the folder. You are not may specify Mail::Internet and MIME::Entity here: they will be translated into Mail::Message messages first.

determineBodyType MESSAGE, HEAD

Determine which kind of body will be created for this message when reading the folder initially.

lineSeparator [STRING|'CR'|'LF'|'CRLF']

Returns the character or characters used to separate lines in the folder file, optionally after setting it to STRING, or one of the constants. The first line of the folder sets the default.

UNIX uses a LF character, Mac a CR, and Windows both a CR and a LF. Each separator will be represented by a "\n" within your program. However, when processing platform foreign folders, complications appear. Think about the Size field in the header.

When the separator is changed, the whole folder me be rewritten. Although, that may not be required.

locker

Returns the locking object.

read OPTIONS

Read messages from the folder into memory. The OPTIONS are folder specific. Do not call read yourself: it will be called for you when you open the folder via the manager or instantiate a folder object directly.

NOTE: if you are copying messages from one folder to another, use addMessages() instead of read.

Examples:

 my $mgr = Mail::Box::Manager->new;
 my $folder = $mgr->open('InBox');             # implies read
 my $folder = Mail::Box::Mbox->new(folder => 'Inbox'); # same
readMessages OPTIONS

Called by read() to actually read the messages from one specific folder type. The read() organizes the general activities.

The OPTIONS are trusted, head_type, field_type, message_type, body_delayed_type, and head_delayed_type as defined by the folder at hand. The defaults are the constructor defaults (see new()).

storeMessage MESSAGE

Store the message in the folder without the checks as performed by addMessage().

updateMessages OPTIONS

Called by update() to read messages which arrived in the folder after it was opened. Sometimes, external applications dump messages in a folder without locking (or using a different lock than your application does).

Although this is quite a dangerous, it only fails when a folder is updated (reordered or message removed) at exactly the same time as new messages arrive. These collisions are sparse.

The options are the same as for readMessages().

write OPTIONS

Write the data to disk. The folder is returned if successful. To write to a different file, you must first create a new folder, then move the messages, and then write the folder.

WARNING: When moving messages from one folder to another, be sure to write the destination folder before writing and closing the source folder. Otherwise you may lose data if the system crashes or if there are software problems.

 OPTION               DEFAULT
 force                <false>
 keep_deleted         <false>
 save_deleted         <false>
force => BOOLEAN

Override write-protection by the access option while opening the folder (whenever possible, it may still be blocked by the operating system).

keep_deleted => BOOLEAN

Do not remove messages which were flagged to be deleted from the folder from memory, but do remove them from disk.

save_deleted => BOOLEAN

Do also write messages which where flagged to be deleted to their folder. The flag is conserved (when possible), which means that the next write may remove them for real.

writeMessages

Called by write() to actually write the messages from one specific folder type. The write organizes the general activities.
