Hi all ! I have several OTRS servers currently working under version 6. All of them are installed under Fedora OS. I am using sendmail to manage the email sending and all is well working. But I noticed that the notifications are not sent (or are not received on our outlook email addresses). And it would be better if the notifications can reach my agents… Yesterday, I have just installed a new OTRS server on another server. I have not yet installed sendmail and I am not able to send email from a ticket in OTRS. That is not a bug for the moment. ;-) But I received the notifications on my outlook email address about those failed email attempt. How is it possible ? How notifications can be sent without sendmail installed ? Why notifications are not sent when sendmail is correctly installed and configured to send emails ? How can I have both working on all my OTRS servers (v6) ? Thanks ! Egareg JAOUEN
