After it gets the first DoS report, it goes through the messages in the
batch and scans them one by one to work out exactly which message called
the problem. So it does that for you already :-)
Take a look at the logs and hopefully it will tell you (2nd time round
on the batch) which message caused it. You might try running in Debug
mode so that it's easier to see what's going on, as then there will only
be 1 MailScanner process running.
