ScanMail has
three types of scans: real-time scans, manual scans, and scheduled
scans. To protect your Exchange environment,
ScanMail scans messages and
their attached files, searching for security risks and undesirable
data. When
ScanMail makes
a detection,
ScanMail automatically
takes action against the detection according to your configurations.
You can configure ScanMail to
scan specific targets and configure actions for ScanMail to take when
it discovers a security risk or undesirable data in the targeted
messages or files. You can also configure ScanMail to send notifications
when it takes actions against security risks and undesirable data.
You can configure ScanMail to
backup a file to the Backup folder before taking action on it. This
is a safety precaution designed to protect the original file from
damage.

Note
Trend Micro recommends
deleting backed up files once you have determined that the original
file was not damaged and that it is usable after ScanMail has executed
an action on it. If the file becomes damaged or unusable, send it
to Trend Micro for further
analysis.
Even if ScanMail has
completely cleaned and removed the virus itself, some viruses damage
the original file code beyond repair.

By default, ScanMail scans
all scannable outgoing, incoming, and stored messages in your Exchange
environment. Scannable files are all files except files that are
encrypted, password protected, or exceed user-configured scanning restrictions.
Scanning all files provides the maximum security possible. However,
scanning every message requires a lot of time and resources and might
be redundant in some situations. Therefore, consider limiting the
files ScanMail includes
in scans.
