Ticketing system with approval or moderation
I am looking for a ticketing system application that:  
- supports POP3 or IMAP email importing  
- **allows inbound/outbound tickets moderation**  
I mean... we have a team of workers and clients but would like to  
  approve the tickets before they are assigned to a worker and  
**especially** approve a worker's reply before it is sent to the customer.

  Do you know any good ticket system apps (any programming language is ok) ?

Thanks
Mike
