When deleting message settings lets you select what

actions should be taken when the whole message is mar-

ked for deletion.

• Delete message body – XMON deletes the body

of the infected message. The recipient will receive the

empty message and also non−infected attachments

• Overwrite message body with virus protocol

– XMON overwrites the message body with a virus proto-

col or a rule description.

• Delete whole message – XMON deletes the

whole message including all attachments

When deleting attachments settings lets you select

what action should be taken when a message is marked

for deletion.

• Truncate file to zero size – XMON truncates the

attachment to zero size and lets the recipient see the at-

tachment file name and type.

• Replace file with virus protocol – XMON repla-

ces the infected file with a virus protocol or rule descripti-

• Delete whole message – XMON deletes the

whole message along with all its attachments

Note: If you can not open the Deleting selection (it is displayed in

grey), it is not supported by your MS Exchange Server version.

Performance

The Performance page lets you select performance

ESET NOD32 Antivirus for MS Exchange Server

• Use NOD32 Control Center scanner - Unlike

all the previous versions that would explicitly use the in-

ternal scanning core for antivirus scanning, version 2.71

brings an option to utilize external Control Center scan-

ning core as well. With 32-bit versions of MS Exchange

Server this feature is optional and it is possible to select

it in the Performance section of the XMON setup. With the

64-bit version of MS Exchange Server it is only possible to

utilize the external Control Center scanning core. Therefo-

re this option is automatically selected and grayed out.

• Number of threads – this parameter lets you

select how many threads should be used for virus scan-

ning. More threads on multiprocessor machines can in-

crease the scanning rate. MS Exchange server provider re-

commends using the following formula to determine the

number of threads used: Number of physical processors

times 2 plus 1 = number of threads used.

• Time limit (for Exchange 5.5) – sets the time in-

terval for running the virus scanner

• Time limit (for Exchange 2000 and higher) – a

time limit for scanning an individual file

• Folder to store temporary files - For the best

performance, we recommend that you configure XMON

to store temporary files on a physical drive other than

the one with the Exchange store. If no folder is specified,

XMON will create temporary files in the system tempora-

ry folder.

Background scan scope option

MS Exchange Server 2007 provides a way to actively

affect antivirus scanning in the background. Therefore the

64-bit XMON module version offers an option to configu-

re the progress and scope of background scanning. Howe-

ver, this option is not available in 32-bit versions of MS

Exchange Server and the XMON module; therefore the ap-

propriate controls are inactive and grayed out

Selecting Scan only messages with attachment will

limit the background scanning scope only to messages

with an attachment. This will also decrease the overall

server load while scanning in the background.

Please note that not all infected messages necessari-

ly come with an attachment. However, this will, not de-

crease protection of the messages in the MS Exchange
