Additional Blocklist Request


Recommended Posts

JT,

Please add "Not Just Another Bogus List dnsbl.njabl.org http://www.njabl.org/" to the available Blocklists on https://webmail.spamcop.net/horde/imp/spamcop/blacklists.php or http://webmail.spamcop.net/horde/imp/spamcop/blacklists.php.

Also, while you are there, please add "except .10" to "SORBS DNSbl" to reflect reality and change "blacklist" to "blocklist" or perhaps "dnsbl" (with mixed case as appropriate) to reflect political realities.

Thanks and Best Regards, Jeff G.

I second the motion! ;)

In fact, I made this suggestion in a (moved) message yesterday, found at:

http://forum.spamcop.net/forums/index.php?...=30entry12897

I've been doing some web-based SC reporting of spams that got through my current settings, and was tantalized by seeing lines like this in the parsing details of the email source IP:

217.233.150.184 listed in dnsbl.njabl.org ( 127.0.0.3 )

217.233.150.184 listed in dnsbl.njabl.org ( 127.0.0.3 )

(not sure why the parser lists the same NJABL result twice)

Anyway, I sure hope that this can be done without too much trouble. :)

I just did a little searching in the old "spamcop-mail" archives and found a thread involving this particular BL that started with this message:

http://news.spamcop.net/pipermail/spamcop-...une/008628.html

there was a lot of back and forth on it, and JT said that it wouldn't work in this message:

http://news.spamcop.net/pipermail/spamcop-...une/008642.html

However, that was over a year ago, eons in Internet time, and it's possible that the NJABL has changed a bit since then. On the NJABL.org site, you'll see that their "dnsbl zones are currently available in query mode" and all entries resolve to one of the following:

127.0.0.2 - open relays

127.0.0.3 - dial-up/dynamic IP ranges*

127.0.0.4 - spam Sources

127.0.0.5 Multi-stage open relays

127.0.0.8 Systems with insecure formmail.cgi or similar CGI scripts which turn them into open relays

127.0.0.9 Open proxy servers

*(Though dnsbl.njabl.org still contains lots of dialup/dynamic listings, no more are being added. All dialup/dynamic additions are being put into the dynablock.njabl.org zone, also available as part of combined.njabl.org)

It looks like some of those zones would be useful. Also, in JT's archived response, he explained that:

we can't use lists which include all dialups because it's perfectly valid for a dialup IP address to be listed as the source of an email

because

we check ALL the IP addresses in an email, not just the IP that connects to us

Hmmm...you mean that the SC system can't be programmed to notice that a message coming from a dynamic IP (as identified by queries to the blocklists) is connecting directly to a mailhost MX (assuming that everyone is eventually converted to having to identify their mailhosts)? Thats' something that would certainly enable a lot more spam to be blocked, I'd think.

Sure, if you promise to guarantee that no IP once identified as being such a type, say dial-up, will never, ever, and I mean never, ever change ....

though I noticed that JT didn't answer the original call for help, although, spending time at his referenced link, it's pretty well stated there ..

I beg to differ. I just did some analysis of the "Blacklists Compared" page that JT cited and I'll post my results as a response in that ridiculously-long thread that now has a misleading title... <_<

My reference and the original "call for help" dealt with the ".10" dial-up classification .... but yes, agreed, take it back to the Topic you started.

ah...I get it....I misread your post. There are still other very unanswered "JT questions" in recent threads other than my own...such as one about mail quotas, one about why messages don't seem to expire out of the Held Mail, etc. I hope he's not done answering just yet. :)
