SetRTSpecialHeaders

Hi everyone
I have a question about SetRTSpecialHeaders => https://docs.bestpractical.com/rt/4.4.4/RT/Action/SendEmail.html#SetRTSpecialHeaders

What is the usage of each of the following header:

X-RT-Loop-Prevention
X-RT-Ticket
X-Managed-by
X-RT-Originator

And if they are disabled in the SendEmail.pm, what happens…??
