Hi, When I compose a mail to a customer, I don't want to send a copy to the PostMaster Mail Account. I search in Sysconfig and I find this option "Ticket::Frontend::ComposeExcludeCcRecipients" in "Ticket -> Frontend::Agent::Ticket::ViewCompose" but changing this option in Yes or No don't change the bcc when OTRS compose a mail. Where can I configure this option ? Also I want a response without signature for a queue and a response with signature for another queue. I find the "ResponseFormat" in "Ticket -> Frontend::Agent::Ticket::ViewCompose" but it's the same for all the queues. So I can't delete the $QData{"Signature"}. I try to configure the queues with no signature but a signature is required when I configure a queue and a signature can't be empty. How can I proceed ? Thanks and regards Claude
