The problem is that your filter *must not* print anything to standard
output. MIMEDefang uses standard output for communication between the
C milter and the Perl scanners; if you print anything to standard output,
MIMEDefang becomes completely confused.
Make sure you redirect standard output (and probably standard error, too)
for any commands you run from your filter.
