pardon me if this has already been posted, but I am getting some embedded ones through that appear to take advantage of some IE "features" <font></font><A href="ht tp:/ /qeepluq.com&ljeabfhtqemxctry4ts73e%2E tho uljth ou1%2Ecom/"> If I have firefox up, this link goes nowhere. IE will actually turn the %2E to a "." and load it up. I have both the exim perl plugin by erik mugele and spamassassin plugin and neither catch it. -----Original Message----- From: Sean Sowell [mailto:sean@twin-dad.com] Sent: Tuesday, May 31, 2005 1:31 PM To: discuss(a)lists.surbl.org Subject: [SURBL-Discuss] Re: embedded image spams On Tuesday, May 31, 2005 0300, Jeff C. wrote: >> Yes, please, if you could mention the ones over the past couple >> days we'll look into them.

Pardon the dramatic title, but hopefully it got your attention. This guy's domain got listed by Outblaze, we removed it, and as thanks this guy paints us as irresponsible. Please help us straighten him out, gently: http://blog.holtz.com/index.php/weblog/comments/blacklisting_blogs/ I gave it my shot. Jeff C. -- Don't harm innocent bystanders.

Hello --- I've been diligently sending full message sources of similar spam to submit.[code](a)spam.spamcop.net these past several days. My account there is set up as a mole to minimze the chance of being joe-jobbed. My understanding is that spamcop adds a point for that URI in spamcop's database, until it exceeds the threshold needed for inclusion in sc.surbl. Then, by way of the URIBL_SC_SURBL rule in SA 3.0.3, more of these things will be caught as spam, since SA assigns >= 3.8 points to each such spam. Am new to these tools, so I hope I've understood the docs and faq pages correctly ... Jeff, I can send you a zip file with a bunch of these recent message sources (my email client is OE6). Or, do you just need a bunch of Date: / Message-ID: / Content-ID: triplets? Sean S. www.twin-dad.com

belgischelotto.be appeared in a 419 scam. Anyone (especially in Europe) know if this is a legitimate domain? Jeff C. -- Don't harm innocent bystanders.

Also, while he is unlikely a "criminal" spammer, his "newletters", if uninvited, contain lots of questionable commercial hype. SURBL or not, my machines won't accept his email newletter. Seems consistant - if you use midphase, you just don't "get it". If he doesn't understand that he doesn't even "own" the domain, he probably can't understand any explaination either.

Help please - SA 3.0.2 and surbl
by roger-surbl-discuss＠rope.net 27 May '05

27 May '05

I am trying to use SURBL with spamassassin 3.0.2 but, even though there seems to be an otherwise unusual length of time to process a message, it is definitely not picking up the http://surbl-org-permanent-test-point.com/ or http://127.0.0.2/ test URLs that I put into a test message. I use a local caching nameserver (djbdns). I invoke spamd with "-d -m5 -s local4 -u smtpd -x" and I have restarted the daemon. My /etc/mail/spamassassin/init.pre contains this line: loadplugin Mail::SpamAssassin::Plugin::URIDNSBL My /etc/mail/spamassassin/local.cf contains the following, with explanations afterwards: ========================================================================= required_score 12 # new #fold_headers 0 allow_user_rules 0 report_safe 0 use_auto_whitelist 0 auto_whitelist_factor 0 use_dcc 0 use_pyzor 0 use_razor2 0 use_bayes 0 use_bayes_rules 0 bayes_auto_learn 0 skip_rbl_checks 0 # normally 1 check_mx_attempts 0 dns_available yes # normally no # URIDNSBL - We don't want the standard URIDNSBLs to be used ifplugin Mail::SpamAssassin::Plugin::URIDNSBL score URIBL_AB_SURBL 13 score URIBL_OB_SURBL 13 score URIBL_PH_SURBL 13 score URIBL_SBL 13 score URIBL_SC_SURBL 13 score URIBL_WS_SURBL 13 #uridnsbl URIBL_MULTI multi-surbl.org. TXT #body URIBL_MULTI eval:check_uridnsbl('URIBL_MULTI') #describe URIBL_MULTI Contains URL In MULTI Blocklist #tflags URIBL_MULTI net #score URIBL_MULTI 13 endif # Mail::SpamAssassin::Plugin::URIDNSBL ========================================================================= Explanation: I am not using any of the features in the first part of the list as you can tell by the "0". In addition, I normally do not use any of the network features, so I have explicitly turned off all of the DNSBL checks by setting the scores to "0" for each of them. All I want to do is run SURBL and do some specific filtering. I have tried the URIDNSBL stuff two different ways. First, I had set the included tests to score "0" and used my own definition, then I changed it to what you see now, to use the stock definitions. Questions: Do I have something defined incorrectly? Have I missed a definition? Anything else? Thanks for any help.

embedded image spams
by Rakesh 27 May '05

27 May '05

Hi I have been bugged a lot by embedded image spams recently, although some of these spams got trapped due URI checks, some managed to pass as well as the url wasn't yet blocked in the SURBLs. I probably found something tht i wanted to share with u guys and try and see if we can trap those spams further on the basis of tht. I have classified those embedded image spams into two classes. Class 1 of image of fulllist of viagra and other meds and Class 2 of image of one liner information on cheap softwares or viagra. I was thinking of if possibly we can understand a common pattern and try and make a ruleset on top of tht so tht we dont have to wait for updates at URIbl, then it would be really some thing good. These image only spams apparently have a prob tht we can trap on :). The loophole is in most of the cases the message id of the mail and the content id or cid of the embedded image is exactly same. For e.g. Message-ID: <1066724820.2422(a)boschkitchencentre.com> Content-ID: <1066724820.2422(a)boschkitchencentre.com> some variations also had something like this Message-ID: <1064962549.5961(a)cal.cybersurf.net> Content-ID: <sivjxu_onzvh_dzdohvo> But thts applicable to class1 of the spams and in class 2 which are just images containing oneliners has some variations. In some cases the content id is smartly tampered but again there is a loophole and here is an example of tht Message-ID: <525F074E3524$72BF31B3$02605c3b(a)comcast.net> Content-ID: <e102605c3b(a)comcast.net> the message id and the content id both contain the domain name of the sending server. And a valid mail that had embedded image in it but was sent from outlook had details something like this From Outlook Message-ID: <002101c55c2f$b3f540a0$bdc809c0@cg> Content-ID: <image001.jpg(a)01C55C5D.CB204210> Frankly I haven't seen how content id appears when images are embedded using other valid email clients like netscape or thunderbird. But if we compare the above set of patterns, what appears is tht if a image is embedded using a client like outlook then "@" appears in the content id of the attachment but the latter part of @ is not the domain name, but has the name of the attachment itself and the messageid is different from the content id, whereas incase of the spammers content ids that appear are either exactly same to tht of the message id, or doesnt have a @ or has the domain name of the server as a latter part of the @ in content id. So my question is can we have rulesets in spamassassin that can compare the sending host domain with the latter part of @ of content id or look for @ in the content id.
