NAME

       cufilter - Filter emails through Mail::CheckUser

SYNOPSIS

       Add the following lines to your ~/.procmailrc:

	 # Filter mail through Mail::CheckUser
	 :0f
	 | /usr/bin/cufilter

DESCRIPTION

       When email messages are filtered through this program using the procmail settings as outlined in the SYNOPSYS, the email address in the
       "From:" header is passed through Mail::CheckUser to ensure validity.  If there is a problem with the email address, the "Subject:" header
       is modified to show which email address failed along with the failure reason.  No messages are lost, but it provides an easy way for the
       mail client to organize, sort, or filter based on the subject tweaks.

EXAMPLES

       Lets say a spammer sends a message with the following headers:

	 From: god@heaven.org
	 To: you@host.com
	 Subject: Happy Pill

       Then the new headers might change to the following:

	 From: god@heaven.org
	 To: you@host.com
	 Subject: [CU!god@heaven.org!DNS failure: SERVFAIL] Happy Pill

       This makes it easy to filter for mail clients.

INSTALL

       This file can be installed into /usr/bin/cufilter and is intended to be utilized through the procmail functionality by adding the following
       lines to your ~/.procmailrc configuration.

	 # Filter mail through Mail::CheckUser
	 :0f
	 | /usr/bin/cufilter

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.
