Can anyone point me in the right direction? Just added another email address for a different queue, pop account works great. OTRS gets the email places in the right queue. All out bound email, or when I generate "compose answer" I get the following error? ERROR: OTRS-CGI-77 Perl: 5.8.8 OS: linux Time: Wed Sep 26 14:03:06 2007 Message: Can't use from: user2@mydomain.com! Enable debug for more info!
