| parp is a powerful, extensible e-mail filter with sophisticated anti-spam capabilities. It's designed as a complete replacement for procmail, is MIME-aware, can perform duplicate removal by message ID, and can access the RBL (Realtime Blackhole List) as part of its spam-detection heuristics. It can also access a DBM-format database of trusted e-mail addresses to ensure that false positives are kept to a minimum. |
