NAME

Courier::Filter::Module::FakeDate - Fake "Date:" message header filter module for the Courier::Filter framework

SYNOPSIS

    use Courier::Filter::Module::FakeDate;
    my $module = Courier::Filter::Module::Header->new(
        forward_tolerance   => {
            # years, months, weeks, days, hours, minutes, seconds
            hours       => 2
        },
        backward_tolerance  => {
            # years, months, weeks, days, hours, minutes, seconds
            days        => 5
        },
        
        ignore_unparseable  => 0,
        
        logger      => $logger,
        inverse     => 0,
        trusting    => 0,
        testing     => 0,
        debugging   => 0
    );
    
    my $filter = Courier::Filter->new(
        ...
        modules     => [ $module ],
        ...
    );

DESCRIPTION

This class is a filter module class for use with Courier::Filter. It matches a message if it has a "Date" header field that lies too far in the future or the past, relative to the local system's time. If the message has a "Resent-Date" header field (see RFC 2822, 3.6.6), that one is examined instead, because the message could simply be an old one that has recently been re-sent, which is perfectly legitimate behavior. In the case of a match, the response tells the sender that their "Date" header is implausible and that they should check their clock. Note: Times in different time zones are compared correctly. Note: When using this filter module, it is essential that the local system's own clock is set correctly, or there will be an increased risk of legitimate messages getting rejected.
