You can use the 

scanconfig

 command to configure the behavior of body and attachment scanning. In 

the following example, the 

scanconfig

 command sets the following parameters: 

MIME types of 

video/*

, 

audio/*

, 

image/*

 are 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 attachment is enabled for metadata scanning. When the scanning engine scans attachments, it 
scans the metadata for the regular expression. This is the default setting.

The attachment timeout scanning is configured for 60 seconds. The default is 30 seconds.

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

The 

application/(x-)pkcs7-mime

 (opaque-signed) parts of a message are converted to 

multipart/signed

 (clear-signed) to provide the message’s content for processing. The default is not 

to convert opaque-signed messages.

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.

Specify whether to bypass all filters in case of a 
content or message filter error.

Specify the encoding to be used if no encoding is 
specified.

Specify whether to convert opaque-signed 
messages to clear-signed (S/MIME unpacking).
