Only show RT e-mail address in the e-mail

How can I have RT show only the e-mail address associated with the queue?

For example if there is a Cc associated with the ticket, how can I
disable RT from showing Cc on the e-mail? I want to prevent anyone
from reply all.

Also how can I extract a Cc from a new e-mail (correspondence) to be
added as Cc in RT?

Thanks.
