Oh.. sorry.. it's a fresh install on CentOS using the latest version of 
MailScanner, Sendmail, SA, and clamav.  I hadn't tried MailScanner 
--debug but I did enable debug within MailScanner.conf (didn't give me 
many hints), but while watching the logs, after it forks off all of it's 
processes, it just seems to sit there.. waiting.  The MailScanner 
processes are definitely running.
