Specifying the maximum file or message size to scan
If your client uses the ICAP protocol or the Native protocol, you can specify a maximum size of files or messages to scan. For messages, the maximum size includes the size of the entire message body and all attachments. For container files, the maximum size includes the container file and all of its contents. The files and mail messages that meet or exceed the maximum file size are blocked.
By default, Symantec Protection Engine has no limits on total file or message sizes.
From version 7.0, Native protocol has been deprecated. Symantec recommends the use of either ICAP or RPC protocol.
