Lots of logged info when using demime condition to block attachment types

I've noticed on my servers that I get way too much info logged to syslog
(what I use to log all exim log data) when the demime ACL condition blocks
an attachment type.

Here's the ACL section that's responsible for blocking the email (BTW, this
is not the MIME ACL - this is being called by the old style DATA ACL):

acl_check_mime:
        accept  authenticated   = *

        deny    message         = Message contains MIME errors:
$demime_reason
                demime          = *
                condition       = ${if > {$demime_errorlevel}{2} {yes}{no}}

        deny    message         = Message contains a blocked attachment:
*.$found_extension
                demime          = exe : com : bat : vbs : pif : lnk : scr

        accept


And here's what I get in the log file:

I never see this kind of logged output unless it blocks an email - all the
other demime conditions used in my ACLs never produce such output that I've
seen.  Is there any way to turn it off?  I just want to see a single line
stating it was blocked because of the attachment - I don't need the full set
of headers (causes lots of unnecessary data in my logfiles, which hit about
200mb a day).

I'm using the latest Exiscan release:
