Yes, and I am considering that or putting in a IIS front door (in addition
to my backup MX which is already IIS) and then using the other program that
I can not think of the name right now.

[Declude.JunkMail] Declude and attachments

Hi-

Many of my users are personnel agencies that send and receive a lot of

I'm having a growing problem with processor usage. Does Declude scan

[Declude.JunkMail] Declude and Spam Review

have not been using Spam Review much and wanted to start using it to
check if the held e-mails in hold2 are Spam or not.

Also I wanted to get some opinions on how Spam Review is working for

Re: [Declude.JunkMail] Declude and attachments

2004-06-17 Thread Rick Davidson
I use  a filter that searches for attachments and causes the email to bypass
further filter tests. For example my filter is called BYPASS and contains
lines like these:

BODY 0 CONTAINS .PDF
BODY 0 CONTAINS Content-type: application/msword
BODY 0 CONTAINS Content-Type: application/pdf
BODY 0 CONTAINS Content-Type: application/rtf
BODY 0 CONTAINS Content-Type: application/vnd.ms-excel
BODY 0 CONTAINS X-MS-Attachment:

Then I have this line at the top of all my filters:
TESTSFAILED END CONTAINS BYPASS

Run the bypass filter before any other filter tests run, this has eliminated
alot of false positives for me especially with PDF files.

You can recover alot of CPU processing time by running your tests in a
logical order, run all your filters that hold or delete mail first and then
use the TESTSFAILED END to stop the filtering process on any messages that
are already flagged for holding or deletion

I just watched it build, max out, and decline.

One instance of Declude, then two, then three, all in the 25%+ range. As
soon as it dropped to two Decludes, Queue Manager came right in at 30-40%,
then the cycles dropped as QueueManager dropped down.

[Declude.JunkMail] New Test possibility

2004-06-17 Thread smb
Scott,

With Declue removing the data between the   in HTML messages to get the
correct wording.   Deasdsdasdadlude = Declude. 

Would a test that counts and/or totals the number of characters between a
single asd or all the aaa's in a message be a viable ne test.

I notice a fair amount of spam that may contain a very common phrase that
may be hard to block ought right like want extra income that is broken up
with a large number of characters between the  

Since Declude is removing the characters between the   to combine the
phrase possibly counting the characters and adding it as a test may help
with some spam.

Just a thought

Re: [Declude.JunkMail] Declude and attachments

2004-06-17 Thread R. Scott Perry

One instance of Declude, then two, then three, all in the 25%+ range. As
soon as it dropped to two Decludes, Queue Manager came right in at 30-40%,
then the cycles dropped as QueueManager dropped down.
It does sound like it is the large files that are causing the problem.
One option would be to temporarily disable the BODY filter with the 200 
lines in it, to see if that prevents the problem with the high CPU usage in 
Declude JunkMail.  That could indeed be causing the problem.

The other would be to use the debug mode (LOGLEVEL DEBUG in the 
\IMail\Declude\global.cfg file) and waiting for one of these files to be 
sent.  We can look at the debug log file entries to get a better idea of 
where the high CPU usage is occurring.

OK, the BODY filter is off.

If the problem continues, I'll set the log level to debug and turn the
filter back on.

Re: [Declude.JunkMail] Declude and attachments

2004-06-17 Thread Matt
Scott,
I've got a lot more BODY filters than Dave has, though I don't feel that 
they are excessive.  I probably have about 1,500 BODY searches, but with 
SKIPIFWEIGHT they only run about 25% of the time.

If Dave is using Declude Virus, I would also look there for the issue.  
Anything besides F-Prot and ClamAV in daemon mode will chug a server on 
a large attachment and it will use up far more processing than Declude 
JunkMail, but it will keep the Declude instance alive for longer.  On 
about 65,000 messages a day currently, we generally see from 2 to 10 
Declude processes running at one time with both F-Prot and AVG enabled 
(much less with just F-Prot).  Disabling AVG results in our average 
processor utilization dropping by 1/3 to 1/2 on heavy load hours.

We're running Declude JunkMail and Hijack. No AV on the mail server,
primarily to keep the load down. We have a firewall antivirus appliance and

Re: [Declude.JunkMail] New Test possibility

2004-06-17 Thread R. Scott Perry

With Declue removing the data between the   in HTML messages to get the
correct wording.   Deasdsdasdadlude = Declude.
Would a test that counts and/or totals the number of characters between a
single asd or all the aaa's in a message be a viable ne test.
That is a good idea (and one we're already working on).  We already 
calculate the percentage of hidden characters (HTML code) to the total 
number of characters, but aren't doing anything with it yet (except logging 
it at the debug level).

[Declude.JunkMail] Content Rules plus/vs. Sniffer?

2004-06-17 Thread Andy Schmidt
Hey Matt:

One question - I know that you have been spending a lot of time programming
content filters.

I'm curious whether you are using Sniffer and whether you found that you
needed all those filters to improve detection over Sniffer rules (which then
makes me wonder why they are not made part of Sniffer) - or whether you are
trying to substitute Sniffer?

Re: [Declude.JunkMail] Declude and attachments

2004-06-17 Thread Dave Doherty
Hi Scott-

My body filter runs last. It's set now to skip messages with attachments
(Thanks, Rick Davidson for that one!). SKIPIFWEIGHT is just above my delete
weight.

I tried to derive from the daily report and WAMLOG how many times the filter
runs, and my best guess is that it runs for around 25% of the messages. It
would be nice to know if that is even close. Sounds like it might be if
SKIPIFWEIGHT drops 80% of yours before the filter runs.

 Scott,

 I've got a lot more BODY filters than Dave has, though I don't feel that
 they are excessive.  I probably have about 1,500 BODY searches, but with
 SKIPIFWEIGHT they only run about 25% of the time.

 If Dave is using Declude Virus, I would also look there for the issue.
 Anything besides F-Prot and ClamAV in daemon mode will chug a server on
 a large attachment and it will use up far more processing than Declude
 JunkMail, but it will keep the Declude instance alive for longer.  On
 about 65,000 messages a day currently, we generally see from 2 to 10
 Declude processes running at one time with both F-Prot and AVG enabled
 (much less with just F-Prot).  Disabling AVG results in our average
 processor utilization dropping by 1/3 to 1/2 on heavy load hours.

Re: [Declude.JunkMail] Declude and attachments

2004-06-17 Thread Matt




Statistics will give you a general idea. We generally hold messages at
a score of 10 or 13, but we stop processing custom filters using
SKIPIFWEIGHT when the score reaches 25 and we separate those messages
from the others since we feel +99.99% confident that they are spam and
this allows us to concentrate on reviewing the small amount that gets
held but scores lower. It's clear that after the RBL's and Sniffer run
over 90% of the spam is already beyond this weight, and our legitimate
message volume is less than 15%, so saying that our filters are run 25%
of the time is an understatement, it's more like 18% on our system.
YYMV of course. We take extra steps to move obvious patterns and
sources from our hold range to a score at or above 25 in order to
lighten the load of reviewing.

Since custom filters in Declude are the costliest in terms of
processing power, having a tight system and using a safe SKIPIFWEIGHT
value (beta/interim releases only) can save you at least 75% of the
load of JunkMail. We have probably about 8,000 lines of custom filters
presently and it only appears to cause spikes on large legitimate
messages which aren't common enough to be problematic at our current
volume. AV scanning however is a problem, one that could be helped
immensely by optimizations within Declude Virus, but that isn't your
problem.

database.  We use our filters to compliment sniffer.

I'm not trying to substitute Sniffer, but I see no reason to be heavily 
dependent on it either.  Sniffer is a critical component on our system 
and it hits 94% to 97% of the messages that we block on a daily basis.  
The results on pure spam is probably a bit higher, but for instance we 
are blocking about 2% of our volume as Joe-Job bounces and there are 
other things that get blocked that aren't technically spam, but is 
garbage, and while Sniffer does hit on much of this stuff, it does in 
lower numbers.

I consider Sniffer primarily to be my substitute for content filtering.  
Instead of tagging the wordage, it tags the links primarily (some 
exceptions of course).  When combined with other filters, it is much 
more powerful than both alone, and the same thing goes of our custom 
filters.  So for instance, if we get a DUL hit plus Sniffer hit, the 
confidence in it being spam goes up and we add extra points for that 
condition as well as many others, this also allows us to lower the 
scores on both Sniffer and DUL hits (and others) because combination 
filters are like multipliers, and they often hit in combination.  At the 
same time however we were finding that a good deal of obvious DUL stuff 
wasn't hitting on the DNSBL's that we use so we started creating our own 
DUL filters based on reverse DNS entries using the new NOTCONTAINS 
functionality (required for this sort of work).  We are now tagging 20% 
more DUL hits as a result, and doing it more reliably than before in 
fact (we defeat the filter when IPNOTINMX is not hit, meaning that an MX 
record has been created for the domain to point to that DUL space, thus 
allowing servers from such space to connect without punishment).  I 
actually consider most of my filters to be technical heuristics 
instead of content filters because I'm looking for patterns in almost 
all of them and not words or phrases.

I've gotten serious about pushing a business model for spam blocking in 
recent months and word-of-mouth combined with old-fashioned sales has 
brought us a good deal of business for a company that hasn't even 
launched a site or done any advertising.  Our spam blocking percentage 
is about 99.7% on our Medium setting (Hold at 13).  While that is 
definitely much better than the big players and impossible to beat 
measureably, I figure that over time the big players will catch up or 
come a lot closer.  What makes us special though is that we have managed 
to segregate the blocked messages so that 99% of it lands in what we 
call Drop (score of 25+) and 1% of it lands in Hold (score of 10 or 
13-24), and along with that comes other associated capabilities.  We are 
able to review our Hold file for every one of our customers on a daily 
basis because the work load is so little, for instance yesterday out of 
just over 52,000 blocked messages,  only 465 landed in our Hold range 
(0.89%).  We advise our customers to review this themselves and by not 
mixing in 100% of the spam for them to review, it makes it much more 
likely that they will do so.  Naturally not all false positives will 
land in our Hold range, but I have never seen a personal message land in 
our Drop range, and it's generally very gray stuff that lands in Drop 
such as some newsletter that uses the services of a company that 
primarily engages in spamming (I've only caught this 3 times in Drop, 
but it should be more than 99.99% accurate).  We try to get all mixed 
sources to land in Hold however, but sometimes Sniffer helps to push 
some over the top and of course we also make mistakes.  Yesterday we 
found and reprocessed 9 false positives (personal E-mail and 
newsletters) out of 52,000 messages blocked, and we resolved the 
conditions that created every one of them so that they would no longer 
have issues.  There was some additional advertising content that is 
questionable that was blocked as well but those things generally require 
more research and are not handled immediately as they are not missed.  
Without Sniffer our accuracy would go down and the size of our hold file 
would go up, and we would leak more spam, but we would survive and 
that's important because we can't become completely dependent on any 
single source of data as that represents a liability.

Sniffer has played a major role in our ability to do all of this, but on 
it's own it's just another tool, albeit one that hits the vast majority 
of spam, and it's up to the administrator to make as much as they can of 
it.  By creating pattern filters and also our own RBL, we are able to 
achieve better differentiation between spam and

RE: [Declude.JunkMail] IP4R DNS lookup

2004-06-17 Thread Andy Schmidt
Hi,

I have used filters to summarize categories of ip4r and other tests.

All the open relay tests will fail ONE filter.  So whether one or 4
black-lists say it's an open relay - it will only get ONE weight.

All the DUL/DUHL will fail ONE filter. So, whether a dial-up or dynamic port
is listed in one or many black-lists - it will only get ONE weight.

This technique allowed me to check against MORE blacklists AND define a
higher weight for each class of blacklist.  I don't have to fear that just
because a dial-up port is widely known it will suddenly fail JUST on that.

Anything besides F-Prot and ClamAV in daemon mode will chug a server on

 It does sound like it is the large files that are causing the problem.

 One option would be to temporarily disable the BODY filter with the
 200 lines in it, to see if that prevents the problem with the high CPU
 usage in Declude JunkMail.  That could indeed be causing the problem.

 The other would be to use the debug mode (LOGLEVEL DEBUG in the

Re: [Declude.JunkMail] TESTSFAILED END Question

2004-06-17 Thread R. Scott Perry

I seen this post below and wanted to implement the TESTSFAILED to exit 
out of one of my body filters based on if another test was already triggered.
Is the below line correct (assuming REVERSEDNSFILTER is one of my filters 
that occurs before the filter I put the below line in)?
TESTSFAILED END CONTAINS REVERSEDNSFILTER
That should work fine.
[2] When that line is matched does it show in the logs?
No, it does not.

Re: [Declude.JunkMail] IP4R DNS lookup

2004-06-17 Thread Darrell \([EMAIL PROTECTED])
It depends on the IP4R tests.  For example SBL/XBL is very reliable and I
weight them high.  However, most the of the IP4R tests we weight low/medium.

Subject: [Declude.JunkMail] IP4R DNS lookup


I was wondering how reliable the ip4r lookups are.  There seems to be a
lot of SPAM that is only failing one of the ip4r test (SORBS, SBL, AHBL,
etc) and no more of the test, hence delivering the SPAM.  Is it safe to
increase the weight of all these test to my deletion weight in order to
stop them from being delivered or are there some false positives that
may be caught?

[Declude.JunkMail] Weight Ranges

2004-06-17 Thread Goran Jovanovic
Scott,

How much extra processing to an e-mail does adding a bunch of weight
range statements like:

WEIGHT1019  weightrange x x 10 19
WEIGHT2029  weightrange x x 20 29
WEIGHT3034  weightrange x x 30 34
WEIGHT3539  weightrange x x 35 39

I really just want these just to report on from the logs rather than
take action on them during e-mail processing. My guess is that it should
not take too much CPU.

Also if I so not want these tests to show up in the %TESTSFAILED%
variable then would I add

HIDETESTS WEIGHT1019 WEIGHT2029..

And would I need to put in the $default$.junkmail file

WEIGHT1019 LOG

I do not want to bother putting a line in the headers but I want to have
them in the log file for reporting.

Thanx
