[ifl.net #3657] Contact at: DNSRBL / Namesystems
Dear All, Despite attempts to contact DNSRBL / Namesystems I'm not receiving any response at all - has anyone on the list any useful contacts? (www.dnsrbl.com) - please reply off list. They're blacklisting one of our mail servers - I think for an issue that must be at least two months old given that they are using an incorrect CNAME in their list which hasn't existed for two at least two months - and I am getting nothing but an automated response from their email addresses.

Mark, I've checked all 3 MXs listed for vevers.net and none of them are listed in any DNSBLs I can see, including dnsrbl.net. http://relays.osirusoft.com/cgi-bin/rbcheck.cgi?addr=213.18.255.195 http://relays.osirusoft.com/cgi-bin/rbcheck.cgi?addr=213.18.248.74 http://relays.osirusoft.com/cgi-bin/rbcheck.cgi?addr=213.18.248.75 I hate to ask the obvious but did you follow the instructions for removal on this page? http://www.dnsrbl.net/getremoved.html Justin

Anyone on the list care to comment on the most effective way to get their mailservers taken off unresponsive RBL's? (other than not let them be on there in the first place). We think we know how this one happened but it would be nice to know so that we can be sure we've plugged the hole - we were never even informed that the server and had been listed in the first place - we found out the hard way. I do think that RBL's operators ought to at least respond to legitimate attempts to clear up issue. Regards Mark -- Mark Vevers.

mark have you seen any 'probes' from dnsrbl.net in response to your 'remove' request. Most RBL's probe with their tests as a response. When the tests don't work (or do work depending on the logic!) they should take you off the RBL fairly shortly. -- Martin Hepworth Senior Systems Administrator Solid State Logic Ltd +44 (0)1865 842300 Mark Vevers wrote:

Well, I've done some digging. I don't see any record of spam from that IP but I do see a piece of spam from a machine in that netblock in December. It would be nice if this DNSBL site would tell you why it was listed or at least provide the message(s) that got a given IP listed.

Typically good DNSBLs are quick to respond as long as the requesters work with them to resolve the issue. It sounds like you have and that dnsrbl.net is just unresponsive. I agree with another poster, ask NANAE for help (news.admin.net-abuse.email). Just remember, we anti-spammers are a sensitive breed but we're more than happy to work with providers as long as they are willing to work with us. Just state the facts and tell them that you can't get a response from dnsrbl.net by following the procedures on their website. That should do it. Oh, and provide the IP in question up front so they can check to see if it has a history. That might speed things along.
we were never even informed that the server and had been listed in the first place - we found out the hard way.
If I was running a DNSBL I wouldn't tell you I listed you either. It's not their job to tell you. They are stating their opinion about an IP. They don't have to tell you when they form or change their opinion about that IP. If you don't want them to state an opinion about your IP, make sure it never does anything that they might wish to state an opinion about.
I do think that RBL's operators ought to at least respond to legitimate attempts to clear up issue.
I agree. They should be responsive. Ideally they'd provide an automated method of removal. That would really only work for misconfigured machines (open relays/proxies/SOCKS boxes, etc..) that can easily be retested to confirm they are fixed. Given how that DNSBL works, I take it that a piece of mail from that MX hit one of their honeypots and caused the listing. Whether that piece of mail was spam, an infected message, or what relies on when the dnsrbl.net start answering their mail. Best of luck Justin

I know a lot of DNSBLs, and I've never heard of this one before, nor do I know anyone who uses it. Are you sure it's worth any effort at all to unlist yourself? Any fool can set up a DNSBL, many fools do, most aren't used by anyone. If someone's using to block mail and you care about sending mail to that recieipient, I'd be more inclined to call the receipient and suggest he or she use some more competently run DNSBLs.

I've heard of it...can't remember why. Perhaps just that they popped up in http://www.sdsc.edu/~jeff/spam/cbc.html which I check from time to time. I haven't had the opportunity to look at their site much since it does "Evil $hit"(TM) that doesn't render in Netscape for Linux and locks up Opera for Linux. I had to use Konqueror just now to see their site.

Or just ask them to whitelist you, but it is kind of annoying that dnsrbl would list your server as a spam source, without making any evidence available on their site suggesting what caused them to form that opinion. ---------------------------------------------------------------------- Jon Lewis *jlewis@lewis.org*| I route System Administrator | therefore you are Atlantic Net | _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________
