Augh. I'm wounded to the quick. <g>
It's really not all that bad because everybody's header line is different.
The spammer isn't going to know 40,000 different headers and custom tailor
his output to each. A header that says "X-CBJ-MailScanner: Found to be
clean" isn't going to get by a server that's looking for "X-ECS-MailScanner:
Found to be clean" or vice versa.
