  • Verifying the correctness of routing and mapping information.
  • Analysing traffic statistics provided by participating networks.
  • A helpdesk to trace and help solving international problems.
  • An information server containing technical data to support MHS managers such as mapping and routing documents, operational procedures, reports and tools.
  • Technical support for networks that joined the coordination service.
  • Organising meetings for X.400 managers.
  • Running a mailing list for MHS managers.
  • Early 1993: SWITCH contracted by RARE (Operational Unit) to offer MHS co-ordination as an operational service.
  • 1994: service ran smoothly but the relevance of X.400 diminished in favour of SMTP and MIME.
  • 1995: a number of NRENs stopped using X.400.
  • 1996: MailFLOW service reduced to a core service, consisting of the provision of mapping tables, routing information and a helpdesk.
  • 1997-1998: service further slimmed down, with only seven customers remaining.
  • April 1998: DANTE took on provision of MailFLOW service in-house to the four remaining customers.
