Event Summary

On September 20 1999, Sendmail released Sendmail 3.0 for the NT Server platform. The product targets small to mid-size organizations and Internet Service Providers and offers interoperability with Open Source Sendmail coupled with familiar NT Administrative Tools and Interfaces. Sendmail 3.0 includes the Sendmail Message Transfer Agent, a Mailing List Server, a POP3 Server and a Message Store.

Market Impact

The Sendmail MTA and Relay Agents are used by 74% (Source: Sendmail) of the approximately 8000 (Source: ISP Watch) ISPs on the web today. Version 3.0 for NT Server extends Sendmail's security capabilities with anti-spam features, and features preventing the server from being used as a relay host. Included in the product is an access-blocking application, which allows system administrators to utilize published "spam-blacklists" to further protect the internal mail recipients. Sendmail 3.0 has an extremely simplified GUI based installation wizard, which requires approximately 10 mouse clicks to complete configuration. The speed in which POP3 connection times process has been improved, offering a 10 fold faster performance than the previous revision 2.5 of Sendmail for NT.

Lotus, Microsoft and GroupWise do not offer built in anti-spam features, but do have anti-relay mechanisms built in. Sendmail was designed to supplement corporate e-mail systems. By implementing a Sendmail MTA, a systems administrator will effectively mask the interior mail system, thereby enhancing security. In addition to enhanced security, the built in anti-spam and anti-relay features will further increase corporate anti-spam and anti-relay implementations.

User Recommendations

Microsoft Windows NT environments will benefit from a Sendmail implementation due to the product's robust MTA and enhanced security features, in addition to enhanced processing speed. The product is priced extremely competitively at $9,995 for 5000 mailboxes, making the product a viable choice for IT executives with a close eye on the bottom line.

The majority of established ISPs are heavily based in UNIX systems and most already have UNIX Sendmail implementations. The 3.0 release is geared for Windows NT Server, which is starting to be implemented by some of the newer ISPs on the Internet today. The product is not specifically geared to the upcoming Windows 2000 Active Directory Service, but will function in the same fashion as it would under the NT Server 4.0 platform. The release of the product is a definite positive for both ISPs and corporations looking to enhance the speed of Internet mail while providing enhanced security.
