Hello Guys! I have been having this strange issue lately. Out of nowhere, emails with the XXX@localhost denomination started to spawn randomly in the CC field of random tickets. The staff swears that they never added those emails. I also tried cleaning the "quick list" of emails that popup suggesting names and emails for the TO, CC and BCC field. But the addresses in question get readded. Now its getting worse. Now random people who have nothing to do with the conversation (aka other user emails) are added to the CC fields at random. Is there a way to disable this popup? Is there a way to eliminate these links from appearing? Information I have so far: Appears random, but happens more on certain queues. ( random addresses get added to CC on ticket reply or ticket created when email has been received) Emails added in the CC field are not in the additional emails of the users in question. So there is no real link between them. Emails have not been added by the user or by the replier as CC. The support center ADDS it when processing the ticket.
