Frequently Asked Questions  (FAQ)

 1) Why should I use the Mail::Box::Manager?

    You can process folders using the Mail::Box::Mbox and Mail::Box::MH
    objects, without a Mail::Box::Manager.  However, using the manager, your
    application will work for any kind of folder because the manager will
    autodetect the type, and because all folder objects share the same
    interface!

    Besides, the manager protects you from opening the same folder
    twice (which may cause `inconvenience'), and can create
    message threads.

 2) What are threads?

    Very confusing, the word `thread' in mail folders has nothing to
    do with the threads of Perl and UNIX.  Some operating systems (and
    Perl) have give one program the possibility to start multiple
    sub-programs within itself.  These are called `process-threads',
    or `threads' for short.

    However, in our context, we speak about `message-threads', which
    describe the relationships between messages.  Each message may
    contain the message-id of a message it is in reply to.  Usually
    they also contain a list of references to all messages with the
    same subject and a logical follow-up.

    Mail::Box is able to give simplified access to `message threads'
    (`threads' for short) via the Mail::Box::Manager.

 3) How can it be that Mail::Box folders show less messages in the
    folder than other applications do?

    Because Mail::Box has support for reading e-mail per thread, it
    keeps an index based on message-id.  Every message shall have
    a unique message-id, so when the same id is found again, that
    message considered to be a copy and ignored.

    By the way: this may remove a lot of spam ;)

 4) How can I fight SPAM?

    Mail::Classifier is a package based on Mail::Box, which can be
    trained to recognize Spam.  SpamAssassin is a rule based spam filter,
    and can be used via Mail::Box::Search::SpamAssassin
