Am I missing something, or is perhaps stream_by_domain() the solution here?

Something that almost looks like Perl...

sub filter_end() {
    if ( stream_by_domain() ) {
        return;
    }
    @LocalDomains = read_localhostnames_table();
    for $dom ( @LocalDomains ) {
        # All recipients are in the same domain, so we only need to
        # compare the first one...
        if ( $Recipients[0] =~ /@$dom$/ ) {
            # do local-domain neat stuff here
            last;
        }
    }
    # Do the stuff that everyone needs
}
