• Delegate access to folders (manager/secretary operation).

• Messages are held in fast user databases with indexing to provide rapid message selection and access.
• Supports thousands of registered users on each Message Server.
• Users may stay connected through periods of inactivity using transparent suspend/resume feature, providing apparent support for thousands of simultaneous users.

• Built-in support for automatic actions such as Delete, Reply, Forward, and Foldering of mail.
• Sophisticated rules-based filters select which messages will trigger a particular action.
• User's may register and define auto-actions and associated filters.

• Auto-forward may be used to pass particular messages on for action by other users.
• Auto-folder can be used to organise incoming mail into different folders.
• Auto-discard allows for the removal of messages which have time expired or been obsoleted.
• All auto-actions are carried out “in the background” by the Messaging Server even when the client is disconnected.
• Reports and notifications are automatically correlated against a journal copy of the originally sent message, allowing a user to track the delivery and read status of a message without the client having to perform "brute-force" correlation.
• Conversation "threads" are automatically linked allowing a client to rapidly follow "Reply" or "Cross-reference" threads between messages without the client having to work out this linkage.

• Open "client-server" architecture, with a choice of user access protocols.
• Multi-protocol access to individual user's message store using single password ("universal logon").
• Microsoft MAPI clients fully supported - including NET-TEL's Universal Information Client.
• Full access from Web browser using the WebMail Access option - For more information see the "WebMail Access" data sheet.
• High performance client access is offered using NET-TEL's "P7-Lite" access over TCP/IP.

• In addition to TCP/IP dial-up, other asynchronous options include APS and NET-TEL proprietary, including PAD connectivity.
• Mobile use proven over GSM digital services.

• Shared access to Manager's message store.
• Secretary may send messages on behalf of Manager.
• Manager and secretary may review each others actions on individual messages.
• Workflow support for exchange of draft messages with annotations ("sticky" notes).
• Alerts based upon changes within the folder hierarchy (not just newly arrived mail).

• User authentication may employ protected passwords, offering protection against disclosure and replay.
• All passwords are held in encrypted form.
• Password "guessing" attacks give rise to an alarm and application of a lock-out period.

• Remote auto-alert on arrival of incoming mail (when connected on-line).
• Personal and shared address books held on the server and accessed via common client-server connection.
• Management utilities available to analyse and adjust user space occupancy.

• A single Messaging Server can communicate with a community comprising thousands of remote MTAs.
• Multiple concurrent connections may be in progress whilst simultaneously routing local mail.
• UIS/Messaging MTAs may be freely mixed with other vendors’ X.400 MTAs in order to build up multi-vendor systems.
• Rapid restart minimises the duration of planned outages.
• Security features available to control the flow of message traffic in the system using privileges and closed user groups.
• Cross time zone support allows message time stamps to be “normalised” in world-wide networks allowing all times to be displayed in a client user’s local time zone.
• Impeccable international character set support including support for the international variants of ASCII together with extended character sets such as ISO 6937, Teletex and General Text (1988) .

• Configurable connection modes to other MTAs. Two Way Alternate mode allows bi-directional message exchange on a single call, whereas Monologue mode allows only outgoing traffic on a call.
• Centralised call charging - using Two Way Alternate dialogue mode to permit a central MTA to be responsible for transmission costs of both incoming and outgoing messages.
• Individual call charging - using Monologue mode to ensure that individual MTAs are responsible for their own communications costsvConnection times may be restricted to preferred time bands.
• “Off-peak” communications tariffs may be exploited for lower priority messages by assigning preferred connection time bands to messages of a particular priority.
• All connection costs may be borne by a remote MTA by insisting that the remote MTA is responsible for all transmissions (the remote MTA would use Two Way Alternate mode to submit and receive messages at its own expense).
• A “poll period” facility is available so that a remote MTA can poll the central MTA for new messages (using Two Way Alternate mode) even though it has none to transmit.

• Loading can be limited by adjusting the maximum simultaneous communications connections to other MTAs, as well as adjusting the total incoming and outgoing associations to a particular MTA.
• Fine tuning of transmission characteristics caters for variable quality network connections (i.e. by configuration of recovery and checkpointing).
• Incoming associations temporarily refused when free disk space falls below a given threshold.
• After a temporary connection failure to a remote MTA (e.g. on network error) further attempts are made at ever increasing time intervals until a configurable time limit is reached. Thereafter further attempts are made at the maximum time interval.
• In the event that a remote MTA is temporarily busy (communications connection successful), further attempts will be made after configurable, short time delays.
• An alternative MTA can be specified for use if the configured time limit for connection failures is reached. All currently queued and subsequent messages destined for the original MTA will then be transmitted to the alternate instead. At regular time intervals, attempts are made to revert to use of the original MTA.

• Internet mail Connector (RFC822 with MIME and NOTARY support).
• cc:Mail, Microsoft Mail, Lotus Notes Connectors with directory synchronisation.
• Support for “industry standard” third-party Connectors using file-sharing message queues.

• A comprehensive inbound and outbound Fax interchange capability.
• Allows facsimile recipients of messages to be treated uniformly with e-mail recipients.
• Word Processor documents can be delivered to facsimile users by using the optional Document Conversion Accelerator to transform the original document into an accurate fax image.
• Multi-channel fax operation.

• Invaluable in support of mixed vendor systems, Connectors and X.400 1984 message downgrade.
• Allows the UIS/Messaging Fax Connector to transmit facsimile images of Word Processor documents.
• Where destination systems have unknown capabilities then the message contents may be reduced to a common denominator (such as the IA5 text repertoire or G3 Fax).
• Document conversions between different processing standards (e.g. incompatible Word Processor formats).
• Complements the 1984 message downgrade feature so that contents appropriate to a 1984 MTA are transmitted.
• Conversions between alternate message attachment types i.e. “Bilaterally Defined”, “Extended” and "File Transfer".
• Text conversions between different character repertoires i.e. “GeneralText”, “Teletex”, ISO 6937 and IA5 .
• Conversion is extensible so that customer-defined programs may be invoked to transform message attachments.
• The Document Conversion Accelerator allows Windows-based applications to be harnessed by a UNIX-based UIS.

• Privilege controls for users, Connectors and remote MTAs allow specific restrictions to be imposed on the use of expensive resources (e.g. an international fax Connector) and specific, costly destinations (e.g. a Value Added Network).
• Virus checking can be performed by employing the UIS/Messaging Virus Scanner to scan message traffic.

• Closed User Groups allow users with inter-communication rights to be managed at the level of individual originator and recipient address pairs.
• Message Route Authentication allows the validation of message origination by association with incoming MTA route.
