NAME

INHERITANCE
Mail::Message::Head::ListGroup
is a Mail::Message::Head::FieldGroup

SYNOPSIS
my $lg = Mail::Message::Head::ListGroup->new(head => $head, ...);

DESCRIPTION
A list group is a set of header fields which are added by mailing-list managing software.
This class knowns various details about that software.
The knowledge and test messages which are used to initially implement this module is taken
from Mail::ListDetector, written by Michael Stevens <mailto:michael AT etla.org>. The logic
is redesigned to add flexibility and use the powerful MailBox features.

DETAILS
Mailing list fields
Detected lists
The Mail::Message::Head::ListGroup class can detect many different mailing lists, some of
which are very popular and some of which are rare.
Numerous fields in a header are added when the message is passed through a mailing list
server. Each list software has defined its own fields, sometimes woth conflicting
definitions. There are also two RFCs about mailing list: "rfc2919" and "rfc2369".
The following lists are currently detected. Between parenthesis is the string returned by
type() when that differs from the software name.

DIAGNOSTICS
Error: Cannot convert "$string" into an address object
The new(address) is coerced into a Mail::Message::Field::Address, which fails. Have a
look at Mail::Message::Field::Address::coerce() to see what valid arguments are.
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.
