Spam Scanning Larger Messages

[Clayton Keller]

I know in 2.6.3 the ability to pass partial messages to SpamAssassin was 
put into place:

"- large messages beyond $sa_mail_body_size_limit are now partially 
passed to SpamAssassin and other spam scanners for checking: a copy 
passed to a spam scanner is truncated near or slightly past the 
indicated limit. Large messages are no longer given an almost free 
passage through spam checks"

Is it possible to revert back to the previous method of not scanning 
these messages? Or is it considered better practice to go ahead and 
provide some scanning giving the attachment and image type spams we see 
periodically these days?
