[rt-users] How do the 'One-time Cc' and 'One-time Bcc' lists get populated

[ktm at rice.edu]

Hi RT Users,

I am trying to clear an address that keeps appearing in the
One-time Cc/Bcc list on the Reply form for a ticket. The user
is no longer here, but the address keeps showing up in the
Reply form for new tickets. How is that list constructed?

Regards,
Ken
