True, but the loop prevention header is already black and blue from our 
non-standards compliant mailclients :-) .
Do you know what value the header would recognize to not send mail?

1) Ok, so I added the Vacation Test info to this page
/path-to-rt3/lib/RT/Interface/Email.pm

# {{{ sub CheckForAutoGenerated
sub CheckForAutoGenerated {
    my $head = shift;

    my $Precedence = $head->get("Precedence") || "" ;
    my $VacTest = $head->get("Subject") || "" ;
    if (($Precedence =~ /^(bulk|junk)/i) OR ($VacTest =~ /(Out of 
Office|vacation)/i)){
        return (1);
    }
    else {
        return (0);
    }     
}

2) I stopped and then started apache

3) Result, I send a test message (Subject: test) all mail doesn't seem 
to get in to create any tickets. 
/var/log/maillog

4) When I undo my changes and stop and start the server again, then the 
mail gets through as normal. 
My Perl knowledge is obviously limited.  Do I need to register the 
module again somehow?
This same result seems to happen everytime I try an experiment on these 
modules.
