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

DESCRIPTION
A spam group is a set of header fields which are added by spam detection and spam fighting software.
This class knows various details about that software.
Extends "DESCRIPTION" in Mail::Message::Head::FieldGroup.
METHODS
Extends "METHODS" in Mail::Message::Head::FieldGroup.
Constructors
Extends "Constructors" in Mail::Message::Head::FieldGroup.
$obj->clone()
Inherited, see "Constructors" in Mail::Message::Head::FieldGroup
$obj->fighter( $name, [$settings] )
Mail::Message::Head::SpamGroup->fighter( $name, [$settings] )
Get the $settings of a certain spam-fighter, optionally after setting them. The knownFighters()
method returns the defined names. The names are case-sensitive.
-Option --Default
fields <required>
isspam <required>
version undef
fields => REGEXP
The regular expression which indicates which of the header fields are added by the spam fighter
software.
isspam => CODE
The CODE must return true or false, to indicate whether the spam fighter thinks that the message
contains spam. The CODE ref is called with the spamgroup object (under construction) and the
header which is inspected.
version => CODE
Can be called to collect the official name and the version of the software which is used to detect
spam. The CODE ref is called with the spamgroup object (under construction) and the header which
is inspected.
example: adding your own spam-fighter definitions
Mail::Message::Head::SpamGroup->fighter( 'MY-OWN',
fields => qw/^x-MY-SPAM-DETECTOR-/,
isspam => sub { my ($sg, $head) = @_; $head->fields > 100 }
);
$obj->from($head|$message, %options)
Returns a list of "Mail::Message::Head::SpamGroup" objects, based on the specified $message or
message $head.
-Option--Default
types undef
types => ARRAY-OF-NAMES
Only the specified types will be tried. If the ARRAY is empty, an empty list is returned. Without
this option, all sets are returned.
$obj->habeasSweFieldsCorrect( [$message|$head] )
Mail::Message::Head::SpamGroup->habeasSweFieldsCorrect( [$message|$head] )
Returns a true value if the $message or $head contains "Habeas-SWE" fields which are correct.
Without argument, this is used as instance method on an existing Spam-Group.
example: checking Habeas-SWE fields
if(Mail::Message::Head::SpamGroup->habeasSweFieldsCorrect($message))
{ $message->label(spam => 0);
}
my $sg = $message->head->spamGroups('Habeas-SWE');
if($sg->habeasSweFieldsCorrect) { ... };
use List::Util 'first';
if(first {$_->habeasSweFieldsCorrect} $head->spamGroups)
{ ...
}

DETAILS
Spam fighting fields
Detected spam fighting software
The Mail::Message::Head::SpamGroup class can be used to detect fields which were produced by different
spam fighting software.
• SpamAssassin
These fields are added by Mail::SpamAssassin, which is the central implementation of the spam-
assassin package. The homepage of this GPL'ed project can be found at <http://spamassassin.org>.
• Habeas-SWE
Habeas tries to fight spam via the standard copyright protection mechanism: Sender Warranted E-mail
(SWE). Only when you have a contract with Habeas, you are permitted to add a few copyrighted lines to
your e-mail. Spam senders will be refused a contract. Mail clients which see these nine lines are
(quite) sure that the message is sincere.
See <http://www.habeas.com> for all the details on this commercial product.
• MailScanner
The MailScanner filter is developed and maintained by transtec Computers. The software is available
for free download from <http://www.sng.ecs.soton.ac.uk/mailscanner/>. Commercial support is provided
via <http://www.mailscanner.biz>.
DIAGNOSTICS
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.
