Problems with uri/_foreign
by Matt Yackley 01 May '04

01 May '04

Hi all, I'm hoping that someone can whack me with a clue-stick here. I'm running into problems getting SURBL up and running. System: RedHat 9 SA 2.63 Amavisd-new SpamCopURI 0.14 I downloaded and ran through the install of the SpamCopURI 0.14 package, put my rules in place, and restarted my services. Here is the error that I receive, each time a messae passes through the system: Failed to run SPAMCOP_URI_RBL SpamAssassin test, skipping: (Can't locate URI/_foreign.pm in @INC (@INC contains: lib /usr/lib/perl5/5.8.0/i386-linux-thread-multi /usr/lib/perl5/5.8.0 /usr/lib/perl5/site_perl/5.8.0/i386-linux-thread-multi /usr/lib/perl5/site_perl/5.8.0 /usr/lib/perl5/site_perl /usr/lib/perl5/vendor_perl/5.8.0/i386-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.0 /usr/lib/perl5/vendor_perl) at /usr/lib/perl5/site_perl/5.8.0/URI.pm line 56. ) 1. I re-copied the three .pm files from the source, like the install docs advised. 2. The _foreign.pm file does exist at /usr/lib/perl5/site_perl/5.8.0/uri/_foreign.pm 3. CPAN claims that URI is up to date 4. A quick google search and search of the SURBL archives don't seem to offer much info on this error I'm sure that I'm missing something silly, so any pointers would be great. Thanks, Matt

Good news/bad news on .us ccTLDs
by Jeff Chan 01 May '04

01 May '04

1. Found a list of .us reserved domains at: http://www.nic.us/registrars/fcfs/dotus_reservedlist_v3.zip 2. The list has 50k domains at 1 MB of text uncompressed, so it will probably be somewhat impractical to use on the client side. 3. It only needs to be processed on the data side to make sure none of the .us ccTLDs gets into the SRUBLs, and that's now in place. 4. There are very many more reserved domains as described at: http://www.nic.us/faqs/index.html#list_reserved_names as: > Where can I see a list of reserved .US names? > See http://www.neustar.us/registrars/. In addition to the > specific names contained in this reserved name file, the > following categories of names are also reserved: > > * All numbers five digits and higher > * All numbers in the format five digits-four digits (zip codes) > * All telephone numbers including toll-free numbers > * Tagged domain namesall labels with hyphens in the third > and fourth character positions (e.g. "bq--kn2n4h4b") 5. It's very unlikely that any of these geographic or reserved domains will become a major source of spam hosting. I don't envision city or country registrars handing subdomains under reserved domains to random spammers. I had a heck of a time trying to get the late, lamented Jon Postel to let the City of Mountain View change theirs from mtview or mtnview to mountainview.... I know things are different now, but I still doubt reserved subdomains are going to be handed out like Mardi Gras candy or anything like that. :-) 6. Note that none of this prevents spammerdomain.us from getting onto the blocklists. That will still happen as it should. Jeff C.

[SURBL-Discuss] Re: Don't want to give ham lists for creating whitelists
by Daniel Quinlan 01 May '04

For what it's worth, most of the URLs hitting SURBL in my ham are spam URLs anyway. On Saturday, 140 messages hit BE or WS SURBL out of 14971 total ham in my corpus. Retesting those 140 messages now, only 105 messages hit, so you've probably removed some domains since Friday. Hopefully, because they're not spamming domains. In those 105 messages, there were about 123 hits (40 when looking for unique domain-rule pairs) on 34 different domains as follows: count domain rule 80 xxxxx.xxx URIBL_WS_SURBL 3 xxxxxxxxxx.xxx URIBL_WS_SURBL 2 xxxxxxxxx.xxx URIBL_WS_SURBL 2 xxxxxxxxxxxxxxxxxx.xxx URIBL_WS_SURBL 1 xxxxxxxxxx.xxx URIBL_WS_SURBL 1 xxxxxxxxxxx.xxx URIBL_BE_SURBL 1 xxxxx.xxx URIBL_WS_SURBL 1 xxxxxxxxxxxxxxx.xxx URIBL_WS_SURBL 1 xxxxxxxxxx.xxx URIBL_WS_SURBL 1 xxxxxxxxx.xxx URIBL_WS_SURBL 1 xxxxxxx.xxx URIBL_WS_SURBL 1 xxxxxxx.xxx URIBL_BE_SURBL 1 xxxxxxxxxxxxxxx.xxxx URIBL_WS_SURBL 1 xxxxxxxxxxxxxxx.xxxx URIBL_BE_SURBL 1 xxxxxxxx.xxx URIBL_WS_SURBL 1 xxxxxxxxx.xxx URIBL_WS_SURBL 1 xxxxxxxxx.xxx URIBL_WS_SURBL 1 xxxxxxxxx.xxx URIBL_BE_SURBL 1 xxxxxxxxxxxxxxxxx.xxx URIBL_WS_SURBL 1 xxxxxxxxxxxxxxxxx.xxx URIBL_BE_SURBL 1 xxxxxxxx.xxx URIBL_WS_SURBL 1 xxxxxxxxxxxxx.xxx URIBL_WS_SURBL 1 xxxxxxxxx.xxx URIBL_WS_SURBL 1 xxxx.xxx URIBL_WS_SURBL 1 xxxx.xxx URIBL_BE_SURBL 1 xxxxxxxxxxx.xxx URIBL_WS_SURBL 1 xxxxxxxxxxx.xxx URIBL_BE_SURBL 1 xxxxxx.xxx URIBL_WS_SURBL 1 xxxxxxx.xxx URIBL_WS_SURBL 1 xxxxxxxx.xxx URIBL_WS_SURBL 1 xxxxxxxxxxxxx.xxx URIBL_WS_SURBL 1 x-xxxxxx.xxx URIBL_BE_SURBL 1 xxxxxxxxxxx.xxx URIBL_WS_SURBL 1 xxxxxxxx.xxx URIBL_WS_SURBL 1 xxxxxxxx.xxx URIBL_WS_SURBL 1 xxxxxx.xxx URIBL_WS_SURBL 1 xxxxxxxx.xxx URIBL_WS_SURBL 1 xxxxxxxxxxxxxxx.xxx URIBL_WS_SURBL 1 xxxxxxxxxxx.xxx URIBL_WS_SURBL 1 xx-xxxxxx-xxxxxxxxxx.xxx URIBL_WS_SURBL Most of them look like spam domains. -- Daniel Quinlan anti-spam (SpamAssassin), Linux, http://www.pathname.com/~quinlan/ and open source consulting

Not really once you consider than most of the listed URLs in our ham are actually spam domains being discussed in the context of anti-spam efforts. Looking at URLs in the body is never going to have a perfect S/O ratio -- even non-developers discuss spam, forward funny spam, innocently link to interesting content on primarily spamvertized sites, etc. > I guess it's time to stop asking. :-( There are plenty of ways for you to get whitelist URLs without relying on our corpora. -- Daniel Quinlan anti-spam (SpamAssassin), Linux, http://www.pathname.com/~quinlan/ and open source consulting

I'm very concerned that if people who plan on submitting their corpus results into the SpamAssassin mass-check process for 3.0 will end up with no ham hits whereas your average user will have some. Cheating is not the word I would use, but it would completely completely throw off our GA process by making it look like SURBL cannot ever issue a false positive, screwing over non-developers. Even if you only get results from people who are never going to submitting corpus results, you're going to end up with a very heavy whitelist bias towards technical users, penalizing non-technical users who will have the rule scored too high compared to what it should be. > I'm results oriented. If there are some good hand-checked ham lists, > I see no practical reason why we should not use them to generate > message body domain whitelists. See above. It would be much better if you came up with other methods for generating a whitelist besides using our benchmark data which is comparatively tiny compared to the world of ham. One other note: just because a URL comes out of ham does *not* mean it should be listed in SURBL. I expect spam URLs to be present in some ham, discussion of spam mostly, so there should always be a small false positive rate (and the rules should be appropriately scored).

The corpora have to be sorted by humans to be accurate and runs need to be synchronized so everyone tests the same rules so runs only happen once a day, which is fast enough. We've been doing this for well over a year and it works great. If only we had more active developers working on rules...

This ROCKS!
by Doc Schneider 30 Apr '04

30 Apr '04

Just wanted to say how much this software and spam fighting tool really Rock and rolls them spams into neat little balls and tosses them into never never land. I am on my days off and hope to get some type of stats gathering ditty going. But not sure what stats folks want to see. I had some conversations with Chris "The Big Evil One" and he had some ideas. Am just not sure what direction to pursue. I did join the dev list for SA and sort of got talked into checking the docs for SA 3.0 which I'm slowly working on. Just checking them for proper API coverage in the different modules it is using. So my question to you folks is what sort of statistics would you like to see? Number of rules hit, even if a ham (I always get hungry when talking about ham and spam but I digress) or just total number and the actual rules that are being hit for all spam? And isn't there something already in SA that does these rules and hits? corporra(sic and too lazy to look). Anyway let me know what you all would like and I can whip something up. -- -Doc (The D - Ninja)

I wished for a realtime form of DB or flat file to be updated continuously on rule hits. No grepping thru logs or anything. Simply when an email is sent thru SA, whatever rules hit, increase a counter in a db or flat file for that rule. Seperate db or flat file for ham and spam. This gives live stats on a system.

query failed
by Grant Baxter 29 Apr '04

29 Apr '04

Just installed spamcop uri .14. I ran spamd in debug mode just to make sure everything is alright. For every email I've seen so far I see a bunch of "query failed yahoo.com.sc.surbl.org; query failed ying.com.sc.surbl.org; query failed usda.gov.sc.surbl.org; query failed yahoogroups.com.sc.surbl.org". However, I received one email that shows a hit on "SPAMCOP_URI_RBL " with a value of 3. Did I do something wrong when I set this up? Or is this normal behavior? TIA, grant
