DynaStop is a gpl licensed LINUX utility to examine IP4 based addresses for Exim for the purpose of filtering based upon patternistic rules defined by the administrator.
This can be a pivotal factor in e-mail filtering and server load management as dynamic IP addresses are typically used for dial-up, dhcp, and DSL accounts. All of which have a designated mail exchange server that all outbound mail flows as defined with many if not most large internet Service providers (ISP) such as Road Runner, ATT, Qwest, PacBell, BellSouth, EarthLink, AOL, and many more around the world if their terms of service or acceptable use policy.
With DynaStop, an Exim administrator can filter incoming mail on the basis of whether it is a dynamic IP address, thus reducing system load and resources in processing unwanted mail as all legitimate mail from any given ISP will be sent from a proper mail exchange server.
