Hi ntozier,Sorry, but it appears the problem still exists. Here's what I did this morning to test it:I'm at a customer site today, so I opened up email on their administrator account and sent an email to helpdesk@ at 10 AM. Then I walked away to work on an issue here.When I came back, I had no reply message in the administrator inbox here, but looking at my email account (@ in the logs) I had two messages: One sent to the administrator account on osTicket, and the other sent to me because I'm a member of the support team for the "Ticket Dispatch" department.This prompted me to go look at the Exchange message tracking logs. Since osTicket sends direct via SMTP to the exchange server and does not send via phpMail through postfix on the web server, this is the only place this should be tracked. For reference, I used the following Exchange PowerShell command to locate any instances of the email going out: C:\>get-messagetrackinglog -EventID SEND -Sender "helpdesk@" -Start "3/11/2015 9" -End "3/11/2015 23" -resultsize unlimited -MessageSubject "962614"| select-object sender, timestamp, messagesubject, {$_.recipients} | export-csv "c:\sentmail.csv"The ticket number generated was 962614, which is why I'm filtering for that above.Below is the output of the csv file that came back. It appears that it never sent an email back to the originating email address.#TYPE Selected.Microsoft.Exchange.Management.TransportLogSearchTasks.MessageTrackingEvent"Sender","Timestamp","MessageSubject","$_.recipients""helpdesk@","3/11/2015 10 AM","Support #962614 Created | Cust: Ticket Dispatch | User: Administrator | Subj: Test at 1008","@ @""helpdesk@","3/11/2015 10 AM","Support #962614 Created | Cust: Ticket Dispatch | User: Administrator | Subj: Test at 1008","@""helpdesk@","3/11/2015 10 AM","Support #962614 Created | Cust: Ticket Dispatch | User: Administrator | Subj: Test at 1008","@""helpdesk@","3/11/2015 10 AM","Support #962614 Created | Cust: Ticket Dispatch | User: Administrator | Subj: Test at 1008","@""helpdesk@","3/11/2015 10 AM","Support #962614 Created | Cust: Ticket Dispatch | User: Administrator | Subj: Test at 1008","@"Thoughts? Is this a bug in the pipe.php (or other) code?Thanks in advance!
