We extract tokens for Bayesian analysis.  The qmail bounce message
just includes the entire original MIME-encoded message as a big glob
of plain text.  If you try to tokenize that, you get garbage because
you get MIME boundaries, fragments of Base64-encoding, etc.

So we have a chunk of code that looks at the first line of the message:

        if( defined($line) && ($line =~ /^Hi\.\s+This\s+is\s+the/) )  {
                canit_log("Not tokenizing qmail bounce message for Bayes training");
                return 0;
        }

David.
