So, do you mean that <milter-regex> and <milter-greylist> runs 
concurrently instead of sequentially ?

However, in the above configuration, as I observed from some system log 
excerpt, since a connection had been rejected by
<milter-regex>, the  <spamass-milter> (or spamc )  seemed to receive the 
same connection with NULL content (because it is
rejected by milter-regex in the first phase).
