We are a 2 person IT department and would like to receive an email when a new ticket is created and when a ticket is modified, but do not want to auto assign anyone to the ticket.  Is this possible?

We would like out of office replies to be ignored.  Is this possible?

Finally, when sending an email to open a test ticket, as the requester I am not receiving a confirmation of the ticket being created.  Should the requester be notified when a new ticket is created?  Is there a way to configure SD to notify the requester that their ticket was created?
