The VA FMS is an OpenSource-based total message solution designed to provide reliability, versatility, high performance, and expandability to a multitude of organizations, all the way from medium-sized groups up to large-scale network service providers (even those with million-plus accounts). Built to cover a wide and complex range of product combinations (MTA, POP, IMAP, SPAM countermeasures, etc.) and run on various mail systems, this solution provides a highly flexible answer to your needs.

Features

Superior System Expandability Individual mail system functions (MTA/IMAP/POP/LDAP)are broken into separate components, and message data goes through the NFS server while the user profile data is dealt with by LDAP. This design allows for a very simple process by which servers, etc., can be added to a system when there is an increase in users or in traffic levels, and also helps contribute to improving overall system performance. Reliability at the Service Level FlexMessaging Solution was designed to provide complete redundancy for individual servers (which account for specific mail system functions) and for network equipment as well. Accordingly, as FlexMessaging Solution is designed to allow for uninterrupted service in the case of a localized fault, it is a large-scale mail system solution that truly provides reliability and stability. Flexible MTA Design A flexible MTA (incoming, pop, outgoing, drop, etc.) design means that the individual modules that compose the MTA can be run either on a single server or on separate servers. This allows for a high-degree of flexibility in regard to system size and the amount of traffic, making FlexMessaging Solution appropriate for both smaller organizations and large-scale systems (1 million-plus accounts). Open Source-Based Solution As all components in FlexMessaging Solution are Open Source it possible to develop unique and finely tuned answers, allowing for the creation of additional functions and for dealing with high-volume traffic. Accordingly, the overall system does not become an impenetrable black box and accurate assessments and the appropriate support for system faults and the need for expanded functionality (including the kernel itself) can be provided. Coordinated with other VA Products FlexMessaging Solution uses VA Balance (load balancing program), VA Directory (an LDAP directory), and the VA Core OS. This allows for highly cohesive operations, making for a stable and secure overall system. Likewise, this coordination also facilitates a single and unified support package. Suitable for Enterprise-Class Systems With the addition of a variety of improved and modified functions, FlexMessaging Solution provides a robust and high-performance solution suitable for carrier- and enterprise-class systems, which demand reliability.
