My weighting system is this: <100 No action (27.7% of all mail in Jan 2005) 100 Subject tag (.5% of all mail) (1/3 of this weight range tend to be spam) 200 Hold (.5% of all mail) (I average 1 a month of Ham in hold) 300 Delete (71.3% of all mail)
As I have to draw a line somewhere, I drew the line at 200. Everything held or deleted is considered spam. Everything under 200 is considered ham, I think this is fairly conservative. ----- Original Message ----- From: "Dan Geiser" <[EMAIL PROTECTED]> To: <Declude.JunkMail@declude.com> Sent: Monday, February 07, 2005 4:06 PM Subject: Re: [Declude.JunkMail] Spam tests by months > Scott, > How do you define Ham? > > Thanks, > Dan > > ----- Original Message ----- > From: "Scott Fisher" <[EMAIL PROTECTED]> > To: <Declude.JunkMail@declude.com> > Sent: Monday, February 07, 2005 4:14 PM > Subject: [Declude.JunkMail] Spam tests by months > > > I've compiled my spam test results over the last year to look at test > effectiveness trends. > > If anyone is interested I've posted them on my website.
