Not that e2fsck fixes errors on swap partitions, but it's a good
idea anyway, I guess.

First question:  when you start MailScanner, does it successfully
start and stay running?

Next question:  does it spawn children?  Look at the output of
"ps -ef | grep MailScanner" to see if it does.

Next question:  does it appear to be processing messages?  What is
it logging to syslog?  (Do a "grep MailScanner /var/log/maillog" or
similar.)
