Hi, on OTRS v2.0.4, replies on forwarded mails are added to the ticket as email-external. Thus the customer can read the reply which is normally not wanted. I think a have read some weeks ago that OTRS v2.1 reuses the nomenclature Ticket#xyz-FW for forwarded messages. Through this, replies could be add to the ticket as email-int. But I tested v2.1-beta2 which still have the same behavior like v2.0.4. Did you make any other experience? Any known workaround? Bye, Alex
