Here's what I do at my site, where I don't want a cisclaimer on internal 
mail, but do want it everywhere else.

sub filter_begin () {
    if (stream_by_domain()) {
        # More than one domain -- do nothing!
        return;
    }

sub filter_end ($) {
[more snippage]
    # Add annoying disclaimer to outbound mail
    if (lc ($Domain) eq "wilshire.com") {
        # Local mail -- Leave alone
    } else {
        action_add_part($entity, "text/plain", "-suggest", $disclaimer, 
"disclaimer.txt", "inline");
