Thanks for all the help so far. I have OTRS set up and authenticating agents and customers against our ActiveDirectory server. Awesome! We use MS Exchange as our email server. I've set up the SMTP configuration in OTRS so that tickets and messages get mailed out to agents. However, we'd like our customers (internal employees) to be able to email problems to 'otrs@domain.com' and have OTRS automatically pick up the email and create a ticket. I have created the 'otrs' user in ActiveDirectory and configured an email account for this user. This user can send/receive email fine through our Exchange server. In trying to follow the directions in the Docs ( http://doc.otrs.org/1.3/en/html/receiving-email-cmd.html), I'm getting lost. :-( When I do: shell# cat test-email-1.box | /usr/share/otrs/bin/PostMaster.pl It works fine. The message appears in the queue. So, how do I get messages sent to 'otrs@domain.com' to the OTRS server? Thanks, Robert Aldridge
