Matt, I did add the EICAR at the end of my test text file.  Based on
your suggestion I moved it to the top of the text file and that was
stopped.  Putting the EICAR in the middle kept it from getting caught.
I increased the Max SpamAssassin Size parameter from 30000 to 300000 and
that did not clear the error message.  I will keep looking.

Jeff mentioned looking for "Max Spam Check Size ="  I could not find
that entry in my MailScanner.conf file.  That was also the parameter
that my Google searches refered to.  If it is not present, is that the
default setting?
