We're on a fresh installation of osticket trying to get email piping to work.  Local mail server is MS exchange and people use MAC and Windows outlook clients. Further, we have a forwarding rule in exchange that forwards the inbound ticket email over to our web server's mail system (linux) where the piping happens. To try to isolate the issue, I tried combinations of 3 different front end mail clients, and 2 different back end smtp sending servers.The combination that fails to bring the inline image into the ticket as seen in the web UI of osticket is #1and #4 below. (#3, turns the inline image into an attachment when the image is very small).  Switching to a linux smtp server with the same mac mail client makes it work  See screenshot for what it looks like in OST when it fails to process the image and for when it works fine.If there are any logs I can retrieve let me know and I will find them.  Since this is from the piping I'm not sure where to find logs.summary of results.1) Mac Outlook client (typical 100px image) -> local exchange -> osticketfailed2) Mac Outlook client (typical 100px image)-> linux smtp outbound server -> osticketworked3) Mac Outlook client (tiny 2px size image)-> local exchange -> osticketworked (but image was processed in OST as an attachment - it's not displayed inline)4) Windows 10 mail client (typical 100px image) -> local exchange -> osticketfailed5) Mac Thunderbird client (typical 100px image) -> linux smtp outbound server -> osticketworkedosTicket Version     v1.10 (901e5ea) — Up to dateWeb Server Software     Apache/2.2.15 (Red Hat)MySQL Version     5.5.56PHP Version     5.4.45
