The Internet Exchange Messaging Server (IEMS) is a highly modular and scalable open architecture messaging system. It can be used from small single machine installations to fully distributed systems linking geographically distributed sites into a common set of logical domains. Its various components can be run on a single machine or in a distributed environment. Administrators can install IEMS on Windows 98 and ME (Anti-Virus Detached Machine), NT, 2000, and XP. For Linux administrators, IEMS can be installed on RedHat Linux 6.2 through 9.0; Mandrake 8.2 through 9.1; SCO Linux Server 4.0 (United Linux 1.0); RedFlag, and Cosix (CS&S).

A technical introduction and specifications to IEMS can be found here. In additional all IEMS Documentation is freely downloadable.

Internet Exchange Messaging Server totally integrating spam detection, handling, and decision making across the entire messaging system - from connection controls through to the end user mail client. IEMS spam control measures include SMTP connection controls (site and Internet blacklisting), mail relay, MTA level content analysis, user mail sorting, and user directed Bayesian filtering. Site administrators are able to define site wide spam security policies, while deferring decisions on many of the spam detection methods to the end user, including SMTP connection controls.

This combination of SMTP controls, Content Filters, Bayesian Filters, DNS Blacklists, and the integrated extension of these controls to the end users allows for an extremely flexible protection system, designed to block the maximum number of problem messages with no collateral damage.

Some of the many features include anti-virus scanning, attachment filtering at the MTA level, distribution list manager, batch SMTP, connector modules to legacy mail environments such as Lotus cc:Mail and Notes, and more. Messages can be retrieved from the IEMS Message Store using any standard POP3 or IMAP4 capable client (Outlook Express, Eudora, Evolution, etc), as well as the customizable IEMS Web Mail Client. The Web Mail client also supports private and public address books as well as online file storage through web folders. IEMS also supports Outlook compatible calendaring and scheduling, allowing for a natural migration path from Microsoft Exchange.

IEMS is licensed in either Standard Enterprise Edition or Professional Enterprise Edition modes. Both editions are identical in terms of funcionality with the exception that the Professional Enterprise includes cc:Mail and Lotus Notes connectors and also has the ability to operate across distributed systems.

IMA provides a free public test environment you can log into now to get an immediate feel for the power and flexibility of IEMS or you can download your own copy and test it on your server for free for 30 days.

LSMTP is a high-performance SMTP mail server, specifically designed to deliver large volumes of email. What distinguishes LSMTP from other email delivery systems is its speed and ability to operate on modest hardware. As email lists grow, many organizations find that their mail servers can no longer handle the workload. LSMTP's speed and efficiency can reduce the need for multiple SMTP servers, saving you money and reducing overhead.

This system can can deliver more than 500,000 messages per hour (assuming proper configuration, hardware and bandwidth) on a basic 800 MHz Pentium III system, while an AlphaServer can handle up to 2 million per hour.

L-Soft has been using LSMTP in-house since 1995 to run the largest LISTSERV site in the world, with more than 5 million daily deliveries on a single host, this speaks volumes about LSMTP's reliability.

LSMTP is easy to install and requires no supervision for normal use. However, it provides the administrator with many options to tune for top performance.LSMTP is licensed by threads. The higher the thread limit, the more mail that can be delivered in a shorter time. With the unlimited-thread license, hardware and available bandwidth are the only limiting factors.

There is an evaluation version available to try it out ans see if it fits your bill.
