We had to lower this rule's score here because it was catching our SMTP AUTH'd clients' mail with our spam threshold at 6. Both this rule and DYNABLOCK were firing on a significant portion of my SMTP AUTH'd clients. > I am tempted to change it to something like this: > score RCVD_IN_NJABL_DIALUP 0 0.525 0 1.0 > but I assume there is a valid reason for 3.536. > Could some kind soul please try to explain this to me? The valid reason is probably that you can catch a lot of spam with just the dial-up RBLs. I've had several slip through since I lowerred the scores. -- Scott Lambert KC5MLE Unix SysAdmin [EMAIL PROTECTED]
