What is WebPort?

  • A fully featured E-Mail server appliance based on IMAP (Internet Message Access Protocol).
  • Seamless integration and authentication with Microsoft Active Directory and compatible with any IMAP e-mail client (I.e. Outlook)
  • Easy to use Webmail interface with all the features of Yahoo! Mail and Hotmail.
  • WebDisk extension to allow direct access to a users home area stored on the fileserver (upload/download feature included).
  • Anti-Virus & Anti-Spam modules available.
  • Comprehensive Content Control including scanning of images, attachments and documents (Expected 2nd Quarter 04)

Accessing the WebPort E-Mail Server

Students and teachers may access their e-mail by using their favourite Web browser or by using an IMAP enabled e-mail client such as Outlook or Outlook Express.



Logging In

Every user account in the Active Directory will now have a corresponding e-mail address available in the WebPort. Users can log-in with their usual username and password to access their E-mail.


Accessing E-Mail Messages

Unlike POP3 based mail servers, e-mail is stored on the WebPort server making all your messages accessible through the Webmail interface, wherever you are in the world.

In addition, e-mail can be easily backed up and if necessary monitored for abuse (subject to governing privacy laws).


Clicking on the subject of a message will display the contents of the e-mail, including standard header information (shown below)


Viewing Messages


Clicking on the “WebDisk” icon will allow you to access your home area on the fileserver.

Clicking on a file will download it to your computer and if possible open the associated program.


Accessing Files


Finding Messages & Files

Searching the WebPort is easy using the powerful yet simple “Search” feature. E-mail messages can be searched as well as files on the WebDisk.


Security is Paramount

  • Connections to the WebMail system are encrypted with a 128-bit digital certificate ensuring the connection between the clients browser and the server is secure.
  • Files that are uploaded or downloaded to the WebDisk are automatically scanned for viruses before being stored on the fileserver.
  • Remote access to the server is via Secure Shell (SSH) with strong encryption.
  • The WebPort server can be installed in the DMZ.


The WebPort server can be installed in a variety of ways depending on the flexibility of the firewall and network architecture.

The traditional way is to install the WebPort Appliance on the same subnet as the existing Active Directory Server.

This requires a route from the “public” gateway through to the WebPort Appliance on the local LAN, for ports 443 and 22.


In the DMZ (Demilitarised Zone)

A DMZ is a small network that sits between a trusted Internal network, such as the school LAN, and an untrusted external network, such as the Internet.

The WebPort Appliance can be installed at the DMZ, offering extra protection for the school LAN in the unlikely event of a hacker gaining access to the server.

This requires a route from the DMZ to the Active Directory server for ports 389 and 750.


Powerful, Reliable, Stable

  • 19” Rackmount Chassis with cooling
  • tunnel for fast heat dispersion
  • Intel Pentium IV 2.6Ghz CPU
  • 512Mb DDR Fast RAM
  • Adaptec Serial-ATA Hardware RAID Controller
  • 2x 36Gb Serial-ATA 10,000RPM Hard Disks

Rapid Deployment

  • Each WebPort Appliance has been designed for a minimum of 1500 users, and is limited only by hardware resources and bandwidth.
  • The WebPort can be deployed to multiple schools by simply installing an appliance onsite or into the DMZ.

System Requirements

  • Your own domain name (I.e.
  • Access to a public SMTP server that will relay mail for the domain.
  • Agreement from firewall administrators to allow access to the Web Port appliance from the Internet.
  • A Microsoft Active Directory Server with active user accounts.
