I'm wondering about this one ... Our internal staff uses comments to put information in tickets for co-workers that can't be viewed by customers. Customer information is shared via correspondence.
Last week, a staff member deleted (accidentaly) the requestor of a ticket. There were no other cc's or admin cc's. When the staff member clicked on Reply, RT did not sent a outgoing mail, but the message was flagged as Correspondence. So I would like to make a check that returns an error to the user when he/she tries to reply on a ticket with no watchers. Should I try to do it with a scrip or should I adapt the Email.pm?
