What I've asked:
Where can I switch local support to remote? And where can I find the tickets.email file or what is its code content?
Also in the code of is written
if (!osTicket::is_cli())
die(__('pipe.php only supports local piping - use http -> api/tickets.email'));
First, there stands something from "only supports local piping" not remote. Second you should use "api/tickets.email". But in the directory osTicket/upload/api isn't this file.
Also when pipe.php only supports local piping, where is the remote possibility? And where is this file tickets.email or which code is inside?
