NAME

       Mail::Filter - Filter mail through multiple subroutines

SYNOPSIS

	use Mail::Filter;

	my $filter = Mail::Filter->new( &filter1, &filter2 );

	my $mail   = Mail::Internet->new( [<>] );
	my $mail   = $filter->filter($mail);

	my $folder = Mail::Folder->new( .... );
	my $filter->filter($folder);

DESCRIPTION

       "Mail::Filter" provides an interface to filtering Email through multiple subroutines.

       "Mail::Filter" filters mail by calling each filter subroutine in turn. Each filter subroutine is called with two arguments, the first is
       the filter object and the second is the mail or folder object being filtered.

       The result from each filter sub is passed to the next filter as the mail object. If a filter subroutine returns undef, then "Mail::Filter"
       will abort and return immediately.

       The function returns the result from the last subroutine to operate on the mail object.

METHODS

   Constructors
       Mail::Filter->new([FILTER [, ... ]])

	   Create a new "Mail::Filter" object with the given filter subroutines. Each filter may be either a code reference or the name of a
	   method to call on the <Mail::Filter> object.

   Accessors
       $obj->add(FILTER [, FILTER ...])

	   Add the given filters to the end of the fliter list.

   Processing
       $obj->filter(MAIL-OBJECT | MAIL-FOLDER)

	   If the first argument is a "Mail::Internet" object, then this object will be passed through the filter list. If the first argument is a
	   "Mail::Folder" object, then each message in turn will be passed through the filter list.

       $obj->folder

	   While the "filter" method is called with a "Mail::Folder" object, these filter subroutines can call this method to obtain the folder
	   object that is being processed.

       $obj->msgnum

	   If the "filter" method is called with a "Mail::Folder" object, then the filter subroutines may call this method to obtain the message
	   number of the message that is being processed.
