NU-Mail Features

Standard Version

This version provides the following facilities:

Complete local SMTP/POP3 mail service enabling users connected to a Local Area network to exchange messages between their selves.
Mail forwarding to remote recipients via the Internet using SMTP. This requires an Internet Service Provider that supplies access to a SMTP mail server.
Mail collection from the Internet using POP3 and/or SMTP. This also requires an ISP that allows E-Mail to be collected via POP3 or delivers mail via SMTP). Incoming mail can be collected from multiple POP3 mail boxes provided they are hosted on the same POP3 server.
A Dialer that connects to your ISP periodically to despatch any outgoing messages and collect any incoming mail. This uses Windows Dial Up Networking (DUN).
All messages are encrypted whilst they are stored within NU-Mail to ensure confidentiality.
Graphical user interface to enabling both local and remote configuration of the system. The maintenance/configuration system can be run on any workstation that can establish a TCP/IP connection to the computer that is hosting the Gateway.
Remote Console enabling the Gateway to be monitored and controlled from any workstation that can connect (via TCP/IP) to the computer that hosts the Gateway.
Scheduler that controls when the local mail service is available and the frequency that the ISP is connected to.
Facilities for compressing and backing up the NU-Mail database.
Multiple local e-mail domains.
User audit log.
E-Mail redirection.
The system is based on the Standard SMTP and POP3 Internet protocols enabling the Gateway to be accessed by any other system that uses these protocols.
Users can use any suitable Internet E-Mail Client (WIndows messaging, Outlook, Outlook Express, Eudora, Pegasus etc) to connect to the Gateway.
Can be installed and set up by knowledgeable users (i.e. they need to know the basics of SMTP and POP3 mail).
Automatic generation of replies whenever a message is deposited in a mail box.
Auto response messages can include file attachments.
Robots for generating mail shots, joining mailing lists, leaving mailing lists, running an external program to process messages, generating automatic reply messages, updating address lists. The professional version has a robot for starting scheduled services (SMTP deliveries etc). These robots can are activated when a message is posted to a defined mail box.
Immediate forwarding of urgent messages.
E-Mail address aliasing.
Remote mail box configuration/manipuation using suitable formatted messages.
Full protocol diagnostic log.
Content controls (foul language and allowed/disallowed attachment types).
Standard footer text that can be appended to the bottom of each outgoing message.
Virus scanning using Sophos Sweep.
Wizard to kick start your installation.

Professional Version

The Professional version includes all of the features of the Standard version plus the following:
Full access to the scheduler enabling sophisticated service patterns to be defined for moving messages around multiple networks and establishing distributed E-Mail systems. This is used to control when services are to be available/run and connecting to remote systems (LAN, WAN, ISP, NU-Mail etc) to deliver and collect E-Mail.
A message routing system enabling rules to be defined as to how messages are moved around a multiple network system. These rules are used to determine whether messages are to be delivered locally or forwarded onto another system (ISP, remote network, another instance of NU-Mail etc).
Full schematic view of the system detailing how messages flow through the system and where each feature is applied.
SMTP servers and clients support ETRN enabling messages to be collected using SMTP.
Messages can be optionally delivered using DNS instead of an SMTP relay server.
SMTP servers can optionally reject messages not addressed to a local mail box or a local domain.
SMTP servers can optionally vaildate the HELO/EHLO domain using a DNS lookup.
SMTP servers can be configured to not act as open relay.
SMTP clients support authentication using LOGIN (Microsoft) and CRAM-MD5.
Rejection of large messages when collecting mail using a POP3 client.
Automatic generation of messages whenever a routing rule is invoked to process an incoming message.
Robots to generate messages and start scheduled services. This enables services to be chained together and thus run in a predefined sequence (e.g. an SMTP client forwarding messages onto another network will always run after a POP3 client has collected mail from the Internet). This feature can also be used to implement bi-directional SMTP bewteen two NU-Mail systems using one telephone call.
Robots may be activated whenever a routing rule is invoked to process a message and whenever a scheduled service starts.stops.
Mailing lists can be posted to via the message routing system.
Unwanted message (SPAM) filtering.
Automated database compression and back up.
Remote client configuration enabling users to change basic details of their mail boxes - password and re-direction details.
The ability to run multiple SMTP and POP3 servers on the same machine (each bound to a different network card).
Access to multiple ISPs.
Can be integrated into any other SMTP/POP3 software locally via a LAN/WAN or remotely via Windows DUN.
