RE: Experimental - use my server for your high fake MX record
Or, The spammers will find his host and don't use the highest MX record. Or just remove his host from all the results. My best solution would be: Marc, - Clean up the code - Write a manual howto install so every admin can install it - Write an extra bit of code which will send you all the information WITHOUT the information below. - Everybody who wants it can use your great software and we all win* I have contracts with my customers that I will not use their email for other business then to deliver it to its destination. Some of my customers will get into problems if other people know their contacts. So I can give you all information about an email message without - The from - The to - The body But with all the IP addresses and with the QUIT after 451 status. * we all know you wouldn't use it as a selling point to spammers or do something else with it but can/will you write that into a contract with all other admins. And pay a large sum of money if some data is "found" on the internet. And do we want that type of "silly" contracts. No we want to stop spam and not kill every other spamkiller (application or person) met vriendelijke groet, Maurice Lucas TAOS-IT Paulus Buijsstraat 191 2613 HR Delft www.taos-it.nl<http://www.taos-it.nl/> KvK Haaglanden nr. 27254410 From: Marc Perkel [mailto:[EMAIL PROTECTED] Sent: donderdag 8 mei 2008 19:07 To: Kevin Parris Cc: users@spamassassin.apache.org Subject: Re: Experimental - use my server for your high fake MX record Kevin Parris wrote: Well now, if a spambot actually does start recognizing and avoiding his system, doesn't that mean he wins and the spammer loses? I would say YES! You should make an effort to clean it up so that others *can* install it as a standalone daemon, as I suggested. Why? How long will it be before the spambots explicitly refuse to contact your honeypot if it is listed as an MX for the domain they're attacking? I don't see that happening. If the spammers were that sharp they would send quit and close the connection properly and defeat the meathod rather than defeating just me. But it would cost them some bandwidth and speed to do that. Especially if I added some delays before doing the rejection which would cause the spammer to have to keep the connection open longer which they aren't going to do. I'm going to think about the delay thing. You inspired possibly another good idea.

Spam using local newspapers
Hello, I receive some spam today using parts of local newspapers. Just a mixup from some articals put together so my Bayes won't mark it as spam. This is my first time I see spam using local (Dutch) newspapers for this. Normally it is a English random text. Am I the only one seeing this or are there more (Dutch) users seeing this. -- With kind regards, Maurice Lucas TAOS-IT
Re: Disclaimer of the month
If it is a real fax number of teh spammers maybe we should have a DoS on there fax machine. "This is send from a fax at a post office.

A late reply to this thread and I don't know if this works for this list but have it a try. http://www.ezmlm.org/ezman/ezman2.html 2.4 Adding subscriber aliases(*). ezmlm lists may be set up to only allow subscribers to send messages to the list. This is less secure than moderation, but still keeps most ``garbage'' off the list. Occasionally, a user may wish to send messages from an address other than the subscription address. As a remote administrator, you can add the user's alias to a special ``allow'' database. To add [EMAIL PROTECTED] as an alias to the [EMAIL PROTECTED], send mail to [EMAIL PROTECTED] -unsubscribe and other commands work the same way. The messages ezmlm sends talk about the [EMAIL PROTECTED] mailing list, but of course you know that this is just a figure of speech. On lists that do not have subscription moderation, users can add themselves to the ``allow'' database in the same way. This is documented only briefly in the USER'S manual. Archive access may also be restricted to subscribers. Like subscribers of the list or the digest list, addresses in the ``allow'' database are allowed to access the archive. -- With kind regards, Maurice Lucas TAOS-IT

But maybe we have to have a scoring like this - current SURBL score if only on that list - if on List1 and list2 then not a score of list1+list2 but more like a basic SURBL score + fixed value - if on List1 and list2 and list3 then not a score of list1+list2+list3 but more like a basic SURBL score + 2*(fixed value) 21% of all the SURBL hitting spam hit more then 4 list records. If this where a FN (not very likely but possible) then the score would be to high to compensate but if we use a scoring rule like above then the score of a 4+ hiting spam message would be e.g. basic SURBL score = 3 3*fixed value = 1 score = 6 and maybe with a SURBL list with very low FP score there could be a gain in the fixed value score.

My 5 cents: geocities gets enough money from displaying these sites and have a name which will keep them from getting world wide blacklisted. Now it is only on peoples local blacklist but I like the idea for a world wide (URIBL, SURBL,...) blacklist entry. Maybe a poll on the major blacklist sites could help. When could we change "big and with a lot of good guys" into "big and with a lot of good guys and to much bad guys, so sorry for the few good guys" -- with kind regards, Maurice Lucas TAOS-IT

Maybe we would not want to do a lookup at for example. dig txt spammer=domain.tld.blacklist.tld To check if [EMAIL PROTECTED] is a spammers email address. But only at domain.tld.blacklist.tld and punnish the webmailprovider (most of the time the free providers) with a low score. It doesn't make a message go over the top but if e.g. in every message with a yahoo/hotmail/... address in it which is scanned by SA a line is included with EMAILBLACKLISTYAHOO=0.5 added maybe then someday yahoo will do someting about spammers. Maybe then there could be even a (dangerous and misused but free advertising for the provider) rule which will be a negative scoring rule. I would "love" to see in every spam message spammers mis-using my good name to lower the amount of point. (possible problems like the good-old bayes poisoning) In this example yahoo is used but it could have been any provider. -- With kind regards, Maurice Lucas TAOS-IT

So it will make them money if they aren't being used for this kind of abuse. If we could get e.g. Go Daddy support the idea of greydomaining and they will input the data of new domain names in the database and removing 5-day-refund addresses and payed-addresses then Go Daddy won't be a registrar which will be used by spammers. It will *cost* Go Daddy an amount of marketing items like: - we have x million new domains every day/week/month - we have a grand total of x million domain names - ... But it will *give* them a great support from serious users and admins. They won't register that many domain names but if we, the serious admins, do register we will use and pay for that domain. and I like to give my money to a registrar that is doing whatever it cost to keep the internet usable.

The way SA checks the URI for domainname.us.tt
Hello, I submitted wealthpro.us.MUNGED.tt to uribl but he isn't added because SA will only see us.MUNGED.tt.

RE: I need your spam!
I think a lot of people have reacted the same way. We would love to give you all the info you need, so everyones email is faster/cleaner/less bandwidth. But nobody wants to or can give 100% of his email to some non contracted 3th party. If you give us some programs/source so we could implement it for our own high MX record the results (cleaned of personal info) can be send to some 3th party server. We as email service provider have all signed a contract with our end users that we would not give any information to 3th party's. We do our best to keep the communication less of man-in-the-middle attacks and now we have to introduce a man-in-the-middle. It isn't a attack but it is breaking all our contracts.

SA's rule scores are evolved based on a real-world test of a hand-sorted corpus of fresh spam and ham. The whole scoreset is evolved simultaneously to optimize the placement pattern. Of course, one thing that can affect accuracy is if some spams are accidentally misplaced into the ham pile it can cause some heavy score biasing to occur. A little bit of this is unavoidable, as human mistakes happen, but a lot of it will cause deflated scores and a lot of FNs. The rule scores are optimized for the spam which was sent at the time that version of SA was released (actually, at the time the rule scoreset was calculated). Since then, the static SA rules have become less useful since spammers now write their messages to avoid them. The only rules which spammers cannot easily avoid are the dynamic ones: bayes and network checks (RBLs, URIBLs, razor, etc). On my systems, I raise the scores for the dynamic tests since they are the only ones which hit a lot of today's spam. Very true. Most of the static tests (ie: body rule sets like antidrug) spammers quickly adapt to after a SA release, and they loose some effectiveness over time. Maybe we have to make a separate version of the score-file. So you could install an official SA 3.0.3 release and download a score-file say version 3.0.3-date. And ones every month there will be another official score-file. Spammers can adjust there spam to pass the "static" tests but the score will be changed. And after the score-file change Now we have to wait for 3.0.4 before there will be any change in the static score's With kind regards, Met vriendelijke groet, Maurice Lucas TAOS-IT

Newbie question
Hello, congratulations with the first ASF release I'm just a spamassassin newbie. I get the following in my logfiles debug: bayes: no dbs present, cannot tie DB R/O: /tmp/spamd-4331-init/.spamassassin/bayes_toks debug: Score set 1 chosen. With 4331 my current PID of spamassassin. Is there a way to force spamassassin to write bayes_toks to his homedir? Or do I have some other problems? I had the same problem with 2.64 but I was only testing on the moment so 3.0 is there on the right time ;) With kind regards, Met vriendelijke groet, Maurice Lucas TAOS-IT
two instances of SA3.0 with the same homedir
Hello, I have two instances of spamassassin (3.0) running and both use the same auto_whitelist_path & bayes_path Would this give me some problems?

Re: SURBL in 3.0
OK - I think I have narrowed down what is happening with this, though I don't know why. I have placed my local.cf file in a non-standard directory and I am using the --siteconfigpath=path to point to that directory (where my local.cf file and my own custom rules files are located). For some reason this breaks the SURBL checks. If I run spamassassin without that directive (and use local.cf in its standard installation location), the SURBL checks work fine. Can someone else confirm this? This is with 3.0.0. So that's the reason why I don't see any SURBL checks in the headers (_TESTSSCORES_) I do see "uri tests; score so far=-2.599" in my debug logfile but never any line like: 2.0 URIBL_WS_SURBL Contains a URL listed in sa-blacklist [URIs: ca-t.com] I didn't change anything to Makefile.PL, so it's a simple install with a --siteconfigpath=path for starting spamd A test message with http://surbl-org-permanent-test-point-MUNGED.com/ without "-MUNGED" Give the following result in the debug logfile uri found: http://surbl-org-permanent-test-point-MUNGED.com/ And in the headers X-Spam-Status: No, hits=-2.1 required=7.0 tests=ALL_TRUSTED=-3.3,AWL=3.193, BAYES_20=-1.951 autolearn=ham version=3.0.0 With kind regards, Met vriendelijke groet, Maurice Lucas TAOS-IT

Re: Memory footprint of spamd 3.0
From: "Loren Wilton" <[EMAIL PROTECTED]> Sent: Tuesday, October 05, 2004 7:42 AM Any chance in going back to something that actually worked? I tried running a 2.64 version of spamd, but got a mountain of bayes-related errors. There is an option to only run a single child, which is claimed to be equivalent to the 2.6x implementation. I don't recall the option (something=1), but Theo posted it within the last day here. And I'm almost positive it is in the docs somewhere. Just watching what people have been reporting, I've come to several tentative conclusions on 3.0 as it currently stands: 1.I'm about 70% convinced there is an undiscvered memory leak or other resource leak that has the equivalent result. 2.The copying of the config back and forth with preforking has a few minor but serious problems. 3.There is a problem with spamd children getting hung out to dry on a read that never completes. I had this problem and I'm checking on the moment if I found the "bug". The message was deleted before spamc was killed so with a sleep in my spamc call script I hope to be able to close my problem 4.I suspect that 3.0 is inherently less memory efficient than 2.6x; but probably not by a huge amount. I think that when the first three problems are addressed and solved that 3.0 will become a whole lot more generally usable. With kind regards, Met vriendelijke groet, Maurice Lucas TAOS-IT

I wonder if he is ending the line with to create that confusion. Supposedly a lone not preceded by a is not really a newline for email. But SpamAssassin, thinking 'ix-ishly, does. If so I gotta give the guy credit for being passably clever. I don't think this is the problem because I have fixcrio installed before my qmail daemon to filter of all the bare-LF.

All of the qmail mailserver are only connecting to a higher distance MX server if and only if the lowest MX doesn't accept the connection. And doesn't accept the conenction means no 4xx or 5xx error. just nothing.

But keep in mind that newer hardware may or may not be more energy efficient but it has more processing power. So you can use one faster newer machine with x Watt energy or use several x Watt older machines to do the same task. I now have a new HP DL385G5p using 80Watt running 1 linux server and a windows 2008 server (using ESX). This server is build to be used to replace 4 old machine and be one new machine (Windows 2008) and my old machines don't use less than 20 to 40 Watt a piece. So sometimes it is better to buy new and sometimes it is better to use old hardware. CAVEAT: I one have installed one power supply on the moment. But normally HP have dynamic power and can "shuts down" a not used power supply.
