Hi there! OTRS looks very promising, but I've run into a problem. I cannot answer tickets when i press "empy answer". I'm using the latest otrs rpm on a redhat 9 box. Here is the message from /var/log/httpd/error_log: ModPerl::Registry: Can't call method "address" on an undefined value at /opt/otrs//Kernel/System/Email/Sendmail.pm line 88.! In the browser, before i press the submit button, it looks like the from field is empty (From <>). The same happens if I try to forward a message, BUT if I press split,my address is displayed on the screen. The system is capable to send emails when i transfer i ticket and so on. It seems that there might be a problem of getting the "from address". Anyone have a clue whats going on? I've managed to authenticate against our active directory, and getting customer info from our exchange server, so if I can get the rest to work, I'll be very happy. I'm not a perl programmer, so my capabilities to debug the problem is rather limited. I hope somebody can help! Thanks. Eivind Here is the message displayed in the browser: Server error! The server encountered an internal error and was unable to complete your request.
