Features High performance and secure email engine - Qmail will be chosen to work as the email engine kernel for high performance and secure email delivery. It is widely used by ISPs worldwide for mission critical email systems. Yahoo! Is the world's largest Qmail user providing free email services for millions Internet users.
Free yet powerful anti-spam engine - Pre-installed SpamAssassin (http://spamassassin.apache.org) is an extensible email filter which is used to identify spam. It works with Razor (http://razor.sf.net) and DCC (http://www.ryholite.com/dcc/) community-based anti-spam engines to identify and filter spam emails in great accuracy.
Free yet effective and up-to-date anti-virus - Pre-installed Clam Antivirus (http://www.clamav.net) is the winner of security product in LinuxJournal 2006 Editors' Choice Awards. The review writer wrote, "ClamAV is giving the commercial virus-checking programs a real run for their money. The combination of ClamAV and SpamAssassin has reduced dramatically the amount of annoying (and potentially dangerous) mail sent through our server."
With this year's outbreak of e-mail worms for non-Linux platforms, ClamAV has been getting quite a workout, and Linux admins on mailing lists report that database update times are keeping up with or beating the proprietary alternatives.
Web-based administration - Creation of email accounts, mailboxes, quota limits, vacation messages, email forwarding are conducted via web-based interface.
Webmail interface - A Web-based mail and calendar suite allows users to access to their mailboxes through an intuitive and user-friendly Web interface to increase user efficiency
Multi-domain Support & Scalability - Allows you to host mail for multiple domains on a single server. This gives your network rooms to grow without affecting productivity and is especially useful for service providers with multiple clients who each want their own domains. The server is scalable to thousands of users dependent on system resources.
Administration - The Qmail Administrator makes e-mail management so easy that even a novice can perform account maintenance and other common administrative tasks.
Mailing list and auto-forwarding - Create mailing lists and no-maintenance discussion groups or forwarding can be configured via web-based interface.
Email volume monitoring - Comprehensive breakdown of email traffic volume and network patterns are monitored and displayed in 5-minute, 1-hour, daily, monthly and yearly average form.
Competitive Advantages
Listed below are the competitive advantages of our proposal over Microsoft Windows platform: Secure - Most spyware, trojan horses software, worms and viruses are targeting at Microsoft Windows OSes. Comparatively, Linux is much more stable and safe.
Low-cost - Windows requires client access license and all kind of software to support itself to be an Internet based email server. For example, to match the same features provided by Linux, it requires one to purchase the following software at costs no less than RM7000 - Email server, antivirus, antispam and client access license, excluding hardware (Reference: IMail Server + Unlimited Mailbox Antivirus Plug-in @ www.ipswitch.com).
No renewal cost for anti-spam and anti-virus - Clam antivirus updates its patterns many times per day to provide responsive actions against security issues or virus/worm outbreaks. The SpamAssassin makes good use of Bayesian algorithm to provide self-learning mechanism to fight against spam mails.
Low investment in hardware - Linux requires minimal hardware to run efficiently.
Ease of Remote Management - Linux possesses web-based and terminal based administration tools for ease of management and configuration from remote site. Windows-based solution requires GUI interface, high bandwidth and licensing costs (remote desktop).
