Mailscanner doing the math wrong?

[Hirsh, Joshua]

Hi Chris,

 As far as I understand it, per-user meant that MailScanner was running for
only one person, and not for a domain. AWL works by recording how often a
certain address emails someone. In my case, a spammer would start hammering
away on the server, and after awhile their scores wouldn't be flagged as
spam because AWL had it listed as a frequent sender.

 Hope that helps clear it up a bit.
