How can I set the service desk to automatically create an incident that contains everything in an email. ex. to set the subject of the e-mail in the description of the incident, and set the body of the e-mail in the information text block.
I think this is the default behave when sending an e-mail to SD (subject -> Description; Body -> information text block). Create a e-mail account for SD. Go to the Administrator Console > System Panel > E-mail Properties and set the right values on the General Tab.
