We have been using osTicket for the past 6 months and have encountered an issue where certain tickets do not reopen even after a reply email is received. These tickets remain closed. Upon inspecting the headers of the reply emails, we noticed the presence of a header labeled 'Precedence: list,' which is recognized as an auto-reply email header in your code (specifically, in the static function 'isAutoReply').
Is there a way to resolve this issue, such as removing the 'Precedence: list' header from auto-reply emails, or is my conclusion accurate? Alternatively, could there be another underlying issue causing this problem?
