Hello, all. I have some question about virus mail. I have set viruswall about my domain and all mails should be sent first to viruswall. xxxxx.com. 86400 IN MX 0 viruswall.xxxxx.com. <-- viruswall xxxxx.com. 86400 IN MX 5 mail.xxxxx.com <-- mail server When I see virus mail header, like below. Received: from test.com ([211.117.47.1]) by mail.xxxxx.com (8.11.6/8.11.6) with ESMTP id i5B8DdW02504 for <chulmin2 () xxxxx com>; Fri, 11 Jun 2004 17:13:44 +0900 some virus mails are filtered well at viruswall. but other virus mails are not get through viruswall, and go directly to mail.xxxxx.com. I think. so I think some virus mail ignores MX, right? What's the problem and how can I solve this problem? Thanks in advance.
hi monty, yes viruses and spammers are (partliy) ignoring your dns mx record. i learned it myself some weeks ago as i installed an openbsd with spamd installed in front of the first mail server. it didn't helped worked ether. spam and viruses took the secondary server. so you should deploy your solution on any of your mail servers. buzz --------------------------------------------------------------------------- Ethical Hacking at the InfoSec Institute.
