Enhanced Spam Blocking in EIMS 2.2.1 -- Qualcomm has released version 2.2.1 of Eudora Internet Mail Server (EIMS) for the Mac OS. In addition to bug fixes and feature improvements, EIMS 2.2.1 sports a Dialup Manager to better handle server connections using non-dedicated lines (including those managed by Vicomsoft Internet Gateway) and optional mail filters designed to help block spam. EIMS 2.2.1's filters can reject messages with improper message IDs, that appear by their subjects to be advertisements, or that originate from servers listed in the MAPS Realtime Blackhole List (MAPS RBL), the MAPS Dialup User List (MAPS DUL) or the Open Relay Behavior-modification System (ORBS). These three independent services identify computers and networks that tolerate or actively distribute spam, are part of an ISP's dial-up pool (and thus shouldn't be sending mail to you directly), or are known to have an open mail relay likely to be abused by spammers. Use of these filters is completely voluntary and isn't likely to eliminate all spam sent to your server, but it can make a significant dent. We've had good luck using some of these filters here at TidBITS, although Qualcomm should more fully document anti-spam techniques that EIMS supports. EIMS 2.2.1 is a free upgrade to registered owners of EIMS 2.x; a 495K updater is available for users of EIMS 2.2; earlier versions of EIMS 2.x need to be updated to EIMS 2.2 before updating to 2.2.1 - updaters are available on Qualcomm's Web site. EIMS can be purchased electronically for $249 and requires a 68030-based Mac or better, System 7.1, and Open Transport 1.1.2. [GD]
