Mail::Box::POP3 - handle POP3 folders as client
Mail::Box::POP3 is a Mail::Box::Net is a Mail::Box is a Mail::Reporter
use Mail::Box::POP3; my $folder = new Mail::Box::POP3 folder => $ENV{MAIL}, ...;
Maintain a folder which has its messages stored on a remote server. The communication between the client application and the server is implemented using the POP3 protocol. This class uses Mail::Transport::POP3 to hide the transport of information, and focusses solely on the correct handling of messages within a POP3 folder.

$obj->create(FOLDER, OPTIONS)
Mail::Box::POP3->create(FOLDER, OPTIONS)
It is not possible to create a new folder on a POP3 server. This method will always return false.
false
Option Defined in Default folderdir L<Mail::Box> <not used>
. folderdir DIRECTORY
Mail::Box::POP3->new(OPTIONS)
For authentications, you have three choices: specify a foldername which resembles an URL, or specify a pop-client object, or separate options for user, password, pop-server and server-port.

. access MODE
. authenticate 'LOGIN'|'APOP'|'AUTO'
POP3 can use two methods of authentication: the old LOGIN protocol, which transmits a username and password in plain text, and the newer APOP protocol which uses MD5 encryption. APOP is therefore much better, however not always supported by the server. With AUTO, first APOP is tried and if that fails LOGIN.

$obj->addMessage(MESSAGE)
It is impossible to write messages to the average POP3 server. There are extensions to the protocol which do permit it, however these are not implemented (yet, patches welcome).
undef is returned, and an error displayed. However, no complaint is given when the MESSAGE is undef itself.
undef
$obj->addMessages(MESSAGES)
As useless as addMessage(). The only acceptable call to this method is without any message.
Mail::Box::POP3->appendMessages(OPTIONS)
See "The folder" in Mail::Box
$obj->close(OPTIONS)
$obj->copyTo(FOLDER, OPTIONS)
$obj->delete
It is not possible to delete a POP3 folder remotely: the best we can do is remove all the messages in it... which is the action implemented here. A notice is logged about this.

$obj->listSubFolders(OPTIONS)
Mail::Box::POP3->listSubFolders(OPTIONS)
The standard POP3 protocol does not support sub-folders, so an empty list will be returned in any case.
Option Defined in Default check L<Mail::Box> <false> folder L<Mail::Box> <required> folderdir L<Mail::Box> <from folder> skip_empty L<Mail::Box> <false>
. check BOOLEAN
. skip_empty BOOL
$obj->nameOfSubFolder(NAME)
See "Sub-folders" in Mail::Box
$obj->openRelatedFolder(OPTIONS)
$obj->openSubFolder(OPTIONS)
It is not possible to open a sub-folder for a POP3 folder, because that is not supported by the official POP3 protocol. In any case, undef is returned to indicate a failure.
$obj->coerce(MESSAGE)
See "Internals" in Mail::Box
$obj->determineBodyType(MESSAGE, HEAD)
$obj->getHead(MESSAGE)
Read the header for the specified message from the remote server.
$obj->getHeadAndBody(MESSAGE)
Read all data for the specified message from the remote server.

Warning: A POP3 folder cannot be deleted: it will be emptied.
Each user has only one POP3 folder on a server. This folder is created and deleted by the server's administrator only. A delete can only remove the messages in the folder for you.
Error: Cannot create POP3 client for $name.
The connection to the POP3 server cannot be established. You may see more, related, error messages about the failure.
Error: Cannot find head back for $uidl on POP3 server $name.
The server told to have this message, but when asked for its headers, no single line was returned. Did the message get destroyed?
Error: Cannot read body for $uidl on POP3 server $name.
The message's headers are retreived from the server, but the body seems to be lost. Did the message get destroyed between reading the header and reading the body?
Warning: Changes not written to read-only folder $self.
You have opened the folder read-only --which is the default set by new(access)--, made modifications, and now want to close it. Set close(force) if you want to overrule the access mode, or close the folder with close(write) set to NEVER.
NEVER
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.
Error: Destination folder $name is not writable.
The folder where the messages are copied to is not opened with write access (see new(access)). This has no relation with write permission to the folder which is controled by your operating system.
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.
Error: Folder $name is opened read-only
You can not write to this folder unless you have opened the folder to write or append with new(access), or the force option is set true.
force
Error: Invalid timespan '$timespan' specified.
The string does not follow the strict rules of the time span syntax which is permitted as parameter.
Warning: Message $uidl on POP3 server $name disappeared.
The server indicated the existence of this message before, however it has no information about the message anymore.
Warning: Message-id '$msgid' does not contain a domain.
According to the RFCs, message-ids need to contain a unique random part, then an @, and then a domain name. This is made to avoid the creation of two messages with the same id. The warning emerges when the @ is missing from the string.
@
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 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.
Error: Update of $nr messages ignored for POP3 folder $name.
The standard POP3 implementation does not support writing from client back to the server. Therefore, modifications may be lost.
Error: Writing folder $name failed
For some reason (you probably got more error messages about this problem) it is impossible to write the folder, although you should because there were changes made.
Error: You cannot write a message to a pop server (yet)
Some extensions to the POP3 protocol do permit writing messages to the server, but the standard protocol only implements retreival. Feel invited to extend our implementation with writing.
