[0033] Email trustworthiness: it is used to represent the trustworthiness of the target (for the email system, the target is the sender or sending domain). The lower the email trust value, the more unreliable the target is, on the contrary, the higher the trust value, the more reliable it is. In this mail trust degree judgment system, reliable means that the more reliable the possible probability of a normal mail is, the higher the probability that it is a normal mail, and vice versa, the lower the probability that it is a normal mail.

Abstract

The related garbage mail process system compromises: a garbage mail filter module in SMTP, a virus analysis module, a mail-box monitor 1, a trust database 2, and a trustness level judgment module 3 for calling the trustness value and comparing with the reference value, wherein the filter module modifies the mail trustness value according to all other process results. This invention improves system process capacity, and enhances protection on illegal access.
