摘　　要：Several years ago DESY faced the need to change the Electronic Mail service to support it on a central cluster of servers.The centralized architecture was necessary for deployment of unified internal E-Mail standards,better quality of service and security,To implemnet a new policy for Electronic Mail Service and avoid huge modifications to a few hundreds network nodes,an additional DNS feature has been added to ISC's (Internet Software Consortium)software bind-4.9.7.The DNS servers running at DESY are capable of distingushing between DNS queries coming from inside and outside of the campus netwokr and reply with different list of MX(Mail Exchanger)records.The external hosts always get a list of MX records pointing to the central mail servers while the internal hosts may use different paths for mail exchange within the campus network.A modified version of DNS software has been used at DESY since 1997,It is fully compliant with the original goal of the projcet and shows good operational performance and reliability.
