Chapter 6 Using Message Filters to Enforce Email Policies
The scanconfig command controls the behavior of body and attachment scanning, such as which types
should be skipped when scanning.
Note If you want to scan a MIME type that may be included in a zip or compressed file, you must include list
'compressed' or 'zip' or 'application/zip' in the scan list.
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.
