[rt-users] $ParseMessageForTicketCcs for correspondence?

[Tim Berger]

It appears that $ParseNewMessageForTicketCcs is for new tickets only,
not for ongoing ticket email based correspondence.  I've looked in the
FAQ and archived messages, but I haven't been able to find a clear,
safe, way of adding non-duplicate CC's to a ticket for email
correspondence in a similar manner as $ParseNewMessageForTicketCcs.

Hints anyone?

Sorry if I've missed anything obvious.

Thanks!
