Technicians able to send/submit emails on behalf of requesters

The ability for a technician (ONLY) to send in an email on behalf of a requester (so that the request doesn't appear as coming from the sender/technician). This is useful if a technician is out of the office/on site; the email could have as the first line:
REQ: Fred Bloggs, SUBJECT: Network down, PRIORITY: High
Then the details can go into the body of the email.
It would also be good to be able to update cases using maybe a CASE NUMBER variable in the first line?
