ScanMail for Exchange 3.5 supports both MAPI and the new Virus Scan API and provides administrators with real-time switching between methods. The integration with both APIs provides Trend Micro customers with more efficient inbound and outbound virus detection and removal by scanning all email messages and attachments before they reach an individual user's mailbox, reducing the threat of virus infections.

ScanMail for Exchange 3.5 is in the Beta 2 stage of product development and is scheduled to ship on March 30, 2000.

       ScanMail for Exchange 3.5 features

--   Earlier detection and elimination of auto-executing viruses by
     intercepting and scanning at the Information Store before mail
     hits the Exchange server mailboxes

--   Real-time scanning and blocking of both inbound and outbound
     messages, including previously unknown macro viruses, ensuring
     complete virus protection in the Exchange environment

--   Single instance scanning (smart-scanning) of email messages and
     attachments, intended to provide high reliability, scalability,
     and performance, as messages will only be scanned once,
     regardless of the number of servers, senders, and recipients

--   100% scanning of email messages and attachments before being
     delivered to the individual mailboxes, reducing the potential
     threat of virus infections

--   Active Online Support, enabling administrators to communicate via
     the Web directly with Trend Micro support engineers, providing
     tools to aid in faster virus response and diagnosis, and
     providing direct access to the Trend Micro Solution Bank (a
     database containing hundreds of frequently asked product and
     virus-related questions)

--   Because of the close integration with the Microsoft Exchange
     Virus Scan API, ScanMail for Exchange 3.5 scans for viruses 50%
     faster than the previous version
