4.2.4.3.1

Actions

In this section you can specify the actions to be performed if a message and/or attachment is evaluated as infected.
The Actions to take if cleaning not possible field allows you to block infected content or delete the message. This
action will be applied only if the automatic cleaning (in ThreatSense engine parameter setup > Cleaning) did not
clean the message.
The Message body deletion method option offers the choice to either delete the message body or rewrite the
message body with action information.
Attachment deletion method lets you decide to delete the message, truncate file attachment to zero size or replace
the infected file with action information.
By activating Rescan, you can scan the messages and files that have already been scanned again.
4.2.4.3.2

Performance

In this section you can set the number of independent scan threads used at a single time. More threads on
multiprocessor machines can increase the scan rate. For the best program performance we advise using an equal
number of ThreatSense scan engines and scan threads.
The Response time limit (sec.) allows you to set the maximum amount of time a thread waits for a message scan to
complete. If the scan is not finished within this time limit, Microsoft Exchange Server will deny the client access to the
email. Scanning will not be interrupted and after it is finished, every other attempt to access the file will be successful.
