# This ACL is used after the contents of a message have been received. This
# is the ACL in which you can test a message's headers or body, and in
# particular, this is where you can invoke external virus or spam scanners.

  # one of the "Sender:", "Reply-To:", or "From:" header lines.

  # must install a virus scanner and set the av_scanner option in the
