Dear All, I've experienced a problem: All of my queues have indival email addresses, and the sender account is avalidable. When I compose an answer or forward to other email address, OTRS prompt a error message "Can't use from 'queue-A@exsample.com': 4545.7.3 Client does not have permission to Send As this sender." I have an other OTRS -- Tiger He hpstiger@gmail.com
