REDUCING UNWANTED AND UNSOLICITED ELECTRONIC MESSAGES BY EXCHANGING ELECTRONIC MESSAGE TRANSMISSION POLICIES AND SOLVING AND VERIFYING SOLUTIONS TO COMPUTATIONAL PUZZLES
First Claim
1. In a receiving domain that is network connectable to one or more sending domains, the receiving domain including one or more receiving messaging servers configured to receive electronic messages from sending domains, a method for determining a sending domain'"'"'s electronic message transmission policies, the method comprising:
- an act of receiving an electronic message from the sending domain;
an act of receiving one or more electronic message transmission policies corresponding to the sending domain;
an act of parsing relevant electronic message transmission policies from the one or more received electronic message transmission policies; and
an act of providing the relevant electronic message transmission policies to a message classification module such that the message classification module can make a more reliable decision when classifying the received electronic message.

Abstract
The present invention provides for generating inputs that can be provided to a message classification module to facilitate more reliable classification of electronic messages, such as, for example, as unwanted and/or unsolicited. In one embodiment, a sending messaging server provides an appropriate response to address verification data thereby indicating a reduced likelihood of the sending messaging server using a forged network address. In another embodiment, it is determined if a messaging server is authorized to send electronic messages for a domain. In yet another embodiment, electronic message transmission policies adhered to by a domain are identified. In yet a further embodiment, a sending computer system expends computational resources to solve a computational puzzle and includes an answer document in an electronic message. A receiving computer system receives the electronic message and verifies the answer document.
