Messaging solutions.
Virtual PRMD
The BT Infonet Virtual PRMD (VPRMD) service provides the ability for customers with a mail server on the Internet to exchange EDI messages with the X.400 community. The service operates as a real PRMD on X.400 and will be perceived by X.400 relations as a normal PRMD.
It is available for both organizations that have their own private mail systems and organizations that want to use the BT Infonet IP Mail Service.
The VPRMD service is based on the same messaging platform as IP Mail and is securely connected to 400NET and the public Internet.
VPRMD can also be reached via an IP VPN or leased lines or Frame Relay. The VPRMD service offers the same grade of stability as the IP Mail service.
Availability - Service availability is set at 99.7% measured over a 3-month period (excluding outages for planned maintenance and down time caused by access networks).
Security – Maximum security is ensured by using one single network connection between your private computer system and the fully protected 400Net service.
Reachability – X.400 business partners can still address the original PRMD X.400 address.
Single Point Of Contact – BT Infonet Operations Center acts as the single point of Contact (24 x 7 x 365).
Secure E-Mail - The VPRMD service is provided via secure networks that enable message exchange with the X.400 community. Using one single network connection between your private computer system and the fully protected 400Net network ensures maximum security. This resilient protocol ensures error-free reliability in message transfer with delivery confirmation on request, making IP Mail EDI Messaging ideal for mission critical applications.
Customers may subscribe to the IP Mail EDI service for the amount of traffic they require. Full trace ability of the message flow is available and can be requested additionally.
Non-Delivery Notifications - The service will automatically attempt to deliver a message several times before a Non-Delivery Notification is generated. A Non-Delivery Notification is created for urgent messages after 2 hours.
Delivery Notifications - Customers can request Delivery or Non-Delivery Notifications.
Network management - The VPRMD service is monitored, controlled and managed by BT Infonet's Internet Network Management Centre. This service is part of an integrated portfolio that provides one-stop ordering, provisioning and billing.
Address mapping between SMTP and X.400 - The customer domain name must be unique within the 400Net domain. Business partners and customers within the X.400 environment can use the X.400 address to send messages to the IP Mail EDI customer. The messages will be received in the BT Infonet Managed Mailbox. The IP Mail EDI subscriber includes the X.400 address to reach the users on X.400. The SMTP messages are routed via the IP Mail EDI server to a gateway that converts the SMTP message into an X.400 message. The X.400 addressing is used to map the message to the correct X.400 recipient on 400NET.
Throughput - In 95% of all cases, a first attempt at message delivery will commence within two minutes after the message have been submitted completely. Message delivery measurement is at customer’s mailbox within 400Net, customer’s PRMD within 400Net or gateway in case of delivery through a gateway or third party. In case the destination cannot be reached at first attempt, the message will be resent via a retry scheme.
