This is a good point.  I will make this modification to the document.  I
think it is a good idea to break out the message processing to include the
message header / subject line alterations.

The virus tests container will be moved outside of the MailScanner container
(as spamassassin is) since this is an external process.  How do you think I
can better describe the Attachment / HTML tests?  This block represents the
filename/filetype rules.

Another good point.  The documentation leans towards letting MS perform the
RBL/DNSBL/Spam List checks, I'll push this piece over to the MailScanner
process.

"RBL/DNSBL/"Spam  List"  checks  done by SpamAssassin can be dis-
abled as MailScanner already does them and there is little to be"
