Actually the value for the X-Loop/X-GLoop header doesn't matter. incoming.pl only checks for the existence of the header itself, so you can change the value to anything you want. I did a grep through the code and these are the lines I found you would need to change:
batch/outgoing.pl:183: $top->set('X-Loop' => 'Gossamer Mail');
batch/outgoing.pl:281: $head->set('X-GLoop' => 'Gossamer Mail');
batch/outgoing.pl:282: $head->set('X-Loop' => 'Gossamer Mail');
batch/outgoing.pl:376: $head->set('X-GLoop' => 'Gossamer Mail');
batch/outgoing.pl:377: $head->set('X-Loop' => 'Gossamer Mail');Which corresponds with your findings.

Code:
batch/outgoing.pl:182: $top->set('X-GLoop' => 'Gossamer Mail'); batch/outgoing.pl:183: $top->set('X-Loop' => 'Gossamer Mail');
batch/outgoing.pl:281: $head->set('X-GLoop' => 'Gossamer Mail');
batch/outgoing.pl:282: $head->set('X-Loop' => 'Gossamer Mail');
batch/outgoing.pl:376: $head->set('X-GLoop' => 'Gossamer Mail');
batch/outgoing.pl:377: $head->set('X-Loop' => 'Gossamer Mail');
