Take a look at 4.75.3. It adds a command "processing_messages_alert" 
which runs the command
     MailScanner --processing
which outputs a dump of the table, excluding messages which are only 
being processed for the first time (ie it only prints records for which 
tries>1). The "processing_messages_alert" turns that into an email 
message which it sends to you according to your MailScanner.conf setup.

It's a very simple script, feel free to rip it apart and improve it. You 
can run the command
     MailScanner --processing
yourself, but be warned it will only generate any output if there is 
something to tell you.

In the Linux RPM distributions of MailScanner, that script is run hourly 
to alert the sysadmin that there might be something wrong.
