$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)
 {   ...
 }

$obj->implementedTypes()

Mail::Message::Head::SpamGroup->implementedTypes()

Inherited, see ``Constructors'' in Mail::Message::Head::FieldGroup

$obj->isSpamGroupFieldName($name)

Mail::Message::Head::SpamGroup->isSpamGroupFieldName($name)

$obj->knownFighters()

Mail::Message::Head::SpamGroup->knownFighters()

Returns an unsorted list of all names representing pre-defined spam-fighter software. You can ask details about them, and register more fighters with the fighter() method.

Mail::Message::Head::SpamGroup->new($fields, %options)

Construct an object which maintains one set of fields which were added by spam fighting software.

 -Option  --Defined in                     --Default

trace => LEVEL
type => STRING
version => STRING

$obj->spamDetected( [
BOOLEAN
] )

Returns (after setting) whether this group of spam headers thinks that this is spam. See Mail::Message::Head::Complete::spamDetected().
