IM2 mengikuti anjuran komunitas internet. <http://www.spamhaus.org/faq/answers.lasso?section=ISP%20Spam%20Issues#133> Dynamic IP lists & port 25 blocking - strongly suggested! --------------------------------------------------------- Dynamic IP ranges--dialup, cable, and DSL--are a huge source of spam. The users of those ranges are most vulnerable to attacks by viruses and Trojan Horse proxy software installed by virus infections which turn their computers into botnet zombie spam spewers. Dynamic IP users on your network should send their mail out through your network's outbound customer servers, or through other dedicated outbound "smarthosts" accessible via SMTP AUTH (authenticated) on port 587: RFC2554, RFC2476, RFC4409. The best way to stop the massive amounts of dynamic IP spam is for your network to filter port 25 on dynamic ranges, only allowing port 25 access to your smarthosts (or not even that, if your smarthosts use AUTH). The Messaging Anti-Abuse Working Group (MAAWG) has its recommendations on port 25 blocking here. If you run a NAT gateway, see http://cbl.abuseat.org/nat.html > Karena dahulu tidak ada masalah menggunakan tcp port 25 ISP atau Korporasi yg tidak mengikuti anjuran itu cepat atau lambat public IP nya akan masuk ke PBL list spamhaus.org dan mendapatkan Bad IP reputation dari senderscore.org; shg susah kirim mail kemana-mana. -- syafril ------- Syafril Hermansyah MDaemon-L Moderators, running MDaemon 10.0.5 Harap tidak cc: atau kirim ke private mail untuk masalah MDaemon. --[MDaemon-L]------------------------------------------------ Milis ini untuk Diskusi antar pengguna MDaemon Mail Server.
