Release Notes: Synspam now uses the Netfilter xt_osf module. If your kernel is Linux 2.6.31 or later, this module can probably be loaded and used. A score is attributed to Windows boxes, and it should not be changed, otherwise you might get false positives with some Exchange servers. The synspam_fw.sh script has been added, which is in charge of loading and unloading iptables rules. Arguments can be passed through the command line. A EUID check was added.
Release Notes: The connections filtering code was refactored; further targets may be added in the future. New functions were added to the synspam-report script for average reject score and average accept score, and it no longer makes correlation between spamassassin and synspam. An extra check was added at startup to prevent success messages from being printed when synspam segfaults.
