Algorithmically Determining Store-and-Forward MTA Relays Using DomainKeys

Store-and-forward MTA relaying servers have frequently presented problems to various antispam techniques, such as IPbased reputation or email authentication. Algorithms that find email relaying servers can use knowledge about a domain's outbound IP addresses combined with cryptographic domain authentication frameworks such as DomainKeys. This paper presents one such algorithm.
