That's a problem?

You don't need a global variable.  Setting a global variable in
filter_sender wouldn't work anyway; read the mimedefang-filter(5) man page
carefully, especially the GLOBAL VARIABLE LIFETIME section.

Instead, do something like:

sub filter_begin {
    my ($entity) = @_;
    my $authenticated = ($SendmailMacros{'auth_type'} && $SendmailMacros{'auth_authen'});

    # Do virus scanning here

    if (!$authenticated) {
        # Do spam-scanning here
    }
}

David.
