Do you see the forks?

I get:
mail      5533     1  0 Aug29 00:00:00 MailScanner: starting child

(Not such a busy server)

You should find lines like this too:
Aug 30 06:16:25 netlx094 MailScanner[3204]: New Batch: Found 21 messages
waiting
Aug 30 06:16:25 netlx094 MailScanner[3204]: New Batch: Scanning 1
messages, 21408 bytes

This proves MailScanner has found the correct queue (21 messages in some
state) and starts to process 1 message that is already completely
delivered and not being processed by any other MS process.
