Configure attachment scanning policy

Commit: This command requires a ‘commit’.

Cluster Management: This command can be used in all three machine modes (cluster, group, machine).

Batch Command: This command supports a batch format.

In this example, the 

scanconfig

 command sets these parameters: 

MIME types of video/*, audio/*, image/* are skipped (not scanned for content). 

Nested (recursive) archive attachments up to 10 levels are scanned. (The default is 5 levels.) 

The maximum size for attachments to be scanned is 25 megabytes; anything larger will be skipped. 
(The default is 5 megabytes.) 

The document metadata is scannned. 

Attachment scanning timeout is set at 180 seconds.

Attachments that were not scanned are assumed to not match the search pattern. (This is the default 
behavior.)

ASCII encoding is configured for use when none is specified for plain body text or anything with 
MIME type plain/text or plain/html.

When setting the 

assume the attachment matches the search pattern

 to Y, messages that cannot be 

scanned will cause the message filter rule to evaluate to true. This could result in unexpected behavior, 
such as the quarantining of messages that do not match a dictionary, but were quarantined because their 
content could not be correctly scanned. This setting does not apply to RSA Email DLP scanning.
