Gross is a greylisting server. The features that make gross stand out from other greylisters are: - it's blazingly fast - it's amazingly resource efficient - it can be configured to query DNSBL databases, and enforce greylisting only for hosts that are found on those databases - it can block hosts that match multiple DNSBL's - it can be replicated and run parallel on two servers - It supports Sun Java System Messaging Server, Postfix, Sendmail and Exim.
