Microsoft Exchange Server 2003 (Vsapi 2.5) - ESET MAIL SECURITY 4 - V4.2 FOR MICROSOFT EXCHANGE SERVER Installation Manual

4.2.4.3

Microsoft Exchange Server 2003 (VSAPI 2.5)

This version of Microsoft Exchange Server includes VSAPI version 2.5.
If the Proactive scanning option is checked, new inbound messages will be scanned in the same order in which they
were received.
The Background scanning option allows scanning of all messages in the system background. Microsoft Exchange
Server decides whether a background scan will run or not, based on various factors, such as the current system load,
the number of active users, etc. Microsoft Exchange Server keeps a record of scanned messages and the virus
signature database version used. If you are opening a message that has not been scanned by the most current virus
signature database, Microsoft Exchange Server sends the message to ESET Mail Security to be scanned before
opening the message in your e-mail client.
Since background scanning can affect system load (scanning is performed after each virus signature database update),
we recommend using scheduled scanning outside working hours. Scheduled background scanning can be configured
via a special task in the Scheduler/Planner. When you schedule a Background scanning task you can set the launch
time, the number of repetitions and other parameters available in the Scheduler/Planner. After the task has been
scheduled, it will appear in the list of scheduled tasks and as with the other tasks, you can modify its parameters,
delete it or temporarily deactivate the task.
If you want to scan plain text messages, select the Scan plain text email bodies option.
Enabling the Scan RTF email bodies option activates scanning of RTF message bodies. RTF message bodies may
contain macro viruses.
The Scan transported messages option enables scanning for messages that are not stored on the local Microsoft
Exchange Server and are delivered to other e-mail servers through the local Microsoft Exchange Server. If scanning for
transported messages is enabled, ESET Mail Security also scans these messages. This option is only available when the
transport agent is disabled.
NOTE: Plain text email bodies are not scanned by VSAPI.
