Thank you for your quick response Ntozier!Since I also get the email at my ticket@company.com I can say it's just a simple forward.I can read all mail previous mails without having to open any email attachment.I do allow attachments at osticket, but it was no attachment. Attachments are working fine. If it were attachment things like simple email's can't reache the allowed size, which is set to 16 MB.My Reply Seperator Tag is set to:=== Boven deze email antwoorden ===It's not present in the email send, because it's the first email. Reply seperators are only put there after I made a reply, correct? This forward is the first email which creates the new ticket. The forwarded content is from email communication from customer with his webdesigner directly, not via the Osticket system.However, I've just found the setting above the reply seperator:"Strip Quoted Reply:" which is enabled.It says this at the question mark:"If enabled, this will remove preceding correspondence between email communications."Could this be the cause of my issue? Should this be disabled the receive contents of forwarded mails?Because I thought this would only affect email communication between communication within Osticket.
