NAME

Email::Folder::Mbox - reads raw RFC822 mails from an mbox file

VERSION

version 0.860

SYNOPSIS

This isa Email::Folder::Reader - read about its API there.

DESCRIPTION

Does exactly what it says on the tin - fetches raw RFC822 mails from an mbox.

The mbox format is described at http://www.qmail.org/man/man5/mbox.html

We attempt to read an mbox as through it's the mboxcl2 variant, falling back to regular mbox mode if there is no Content-Length header to be found.

OPTIONS

The new constructor takes extra options.

fh

When filename is set to "FH" than Email::Folder::Mbox will read mbox archive from filehandle fh instead from disk file filename.

eol

This indicates what the line-ending style is to be. The default is "\n", but for handling files with mac line-endings you would want to specify eol => "\x0d"

jwz_From_

The value is taken as a boolean that governs what is used match as a message separator.

If false we use the mutt style

/^From \S+\s+(?:Mon|Tue|Wed|Thu|Fri|Sat|Sun)/
/^From (?:Mon|Tue|Wed|Thu|Fri|Sat|Sun)/;

If true we use

/^From /

In deference to this extract from http://www.jwz.org/doc/content-length.html

Essentially the only safe way to parse that file format is to
consider all lines which begin with the characters ``From ''
(From-space), which are preceded by a blank line or
beginning-of-file, to be the division between messages.  That is, the
delimiter is "\n\nFrom .*\n" except for the very first message in the
file, where it is "^From .*\n".

Some people will tell you that you should do stricter parsing on
those lines: check for user names and dates and so on.  They are
wrong.  The random crap that has traditionally been dumped into that
line is without bound; comparing the first five characters is the
only safe and portable thing to do. Usually, but not always, the next
token on the line after ``From '' will be a user-id, or email
address, or UUCP path, and usually the next thing on the line will be
a date specification, in some format, and usually there's nothing
after that.  But you can't rely on any of this.

Defaults to false.

unescape

This boolean value indicates whenever lines which starts with

/^>+From /

should be unescaped (= removed leading '>' char). This is needed for mboxrd and mboxcl variants. But there is no way to detect for used mbox variant, so default value is false.

seek_to

Seek to an offset when opening the mbox. When used in combination with ->tell you may be able to resume reading, with a trailing wind.

next_message

This returns next message as string

next_messageref

This returns next message as ref to string

tell

This returns the current filehandle position in the mbox.

next_from

This returns the From_ line for next message. Call it before ->next_message.

messageid

This returns the messageid of last read message. Call if after ->next_message.
