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


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


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

The mbox format is described at

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.


The new constructor takes extra options.

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"

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

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 Content-Length Considered Harmful

 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.

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.

This returns the current filehandle position in the mbox.
