I find most of the spam eminating from people are throught trojaned
computers nowadays. I think the only way to 'detect' these automajically
is to use a proxy for SMTP and allow no direct port 25 attachments
'from' an 'internal machine. You can then scan the email and react
accordinly.

Or maybe I'm talking out the wrong end of my alimentary canal as per usual?
