RE: Experimental - use my server for your high fake MX record

2008-05-08 Thread Maurice Lucas
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)

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

2006-10-23 Thread Maurice Lucas
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

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.

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"

Picking up an old thread.

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.

DomainKitting must cost good registrars like Go daddy a lot of money due
to resource use. 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.

If Go Daddy does give the data of all the registrations there isn't any
need for whois queries.

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.

I know there are some domains which use a 2 level tld zone. like .co.uk

Is this not an TLD which has be to changed inside SA to a 2 level tld?

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

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

If one's wrong, they are ALL wrong.

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

Re: SURBL in 3.0

2004-09-30 Thread Maurice Lucas
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/

Give the following result in the debug logfile

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.

SA 3.0.2? Why no mail from announce@spamassassin.apache.org

2004-12-19 Thread Maurice Lucas
By just checking the SA website I found out that there is a 3.0.2 release 
from 2004-12-16.

Why isn't there an announce from the announce list?

SA 3.1.0-rc1 and rc2: Extra LF in headers

2005-09-13 Thread Maurice Lucas

Hello,

I have a problem with both 3.1.0-rc1 and 3.1.0-rc2.

Some off my mail is checked by SA and marked as spam but gets an extra LF 
causing the rest of my tools to ignore the X-Spam-Status header field.


This is a sample message, I do have more for developers. This problem isn't 
occuring on every email but on a few a day.

One of the strange things in this message is the generation of the message 
ID.

Message-ID: <[EMAIL PROTECTED]>
This ID is generated by my inhouse exchange server
The same with this header
Message-ID: <[EMAIL PROTECTED]>

So there are two Message-ID headers in this mail but only one is in the 
headers the other is in the body.


Another strange thing with all these messages is the insertion of the 3D 
before every score.

THAT may explain what the mad Russian is doing with these high scoring

He found a hole that affects systems that use the X-Spam-Flag for 
something

important. (I don't. I route via the spam message in the subject.)

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.

Leo.  There are a good 9 or 10 variations on this now.  The SARE

I've been testing this for a couple of weeks now, and have had no

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.
If there is a connection made to a listening device then a higher mx is
never tried

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.
