Hallo, Sejak minggu lalu beberapa DNS-BL host (spt spamhaus.org) dan Antispam host (misalkan SURBL) di serang DDOS (Distributed Denial of Service). Implikasinya query ke DNS-BL host menjadi lambat sehingga mail sulit masuk akibat time out.
Silakan melakukan check ke DNS-BL host MDaemon Anda (security | DNS Black List | DNS-BL Host), hapus semua DNS-BL host yg sudah tidak lagi berfungsi, lihat arsip : http://www.mail-archive.com/[email protected]/msg10180.html http://wiki.blitzed.org/OPM_status perbaiki setting DNS-BL host Anda, lihat arsip : http://www.mail-archive.com/[email protected]/msg11267.html http://www.mail-archive.com/[email protected]/msg11272.html perhatikan pula setting DNS (setup | Primary Domain | DNS) pastikan IP yg Anda isikan disitu valid karena baik DNS-BL maupun Spamassassin BL host (URIBL dan SURBL) menggunakan setting tsb sekalipun Anda mengaktifkan "try to use DNS servers define in windows TCP/IP setting". Kalau Anda melihat incoming mail "merangkak" (crawling), ubah set DNS availability ke No (security | spam filter | Spam Filtering). Kalau Anda bisa running DNS cache sendiri tentu akan lebih baik karena akan mempercepat DNS-BL/URIBL/SURBL query dan caching. -------- Original Message -------- Subject: [md-beta] FYI: RBLs under attack Date: Tue, 12 Jun 2007 00:51:18 -0500 From: [EMAIL PROTECTED] <[EMAIL PROTECTED]> Reply-To: [EMAIL PROTECTED] To: <[EMAIL PROTECTED]> FYI: Several RBLS are under DDOS attacks http://www.theregister.co.uk/2007/06/11/anti-spam_ddos/ http://www.eweek.com/article2/0,1895,2143566,00.asp http://www.pcmag.com/article2/0,1895,2144550,00.asp http://www.techworld.com/security/news/index.cfm?newsID=9110&pagtype=all Attack types are mutating fast...
