Using Declude - setup basics

Problem reported by Steve Guluk - 2/9/2018 at 9:55 AM

Submitted

Hello,

Is anyone using Declude and found documentation on installation and writing your own rules?
I've reviewed (http://mailsbestfriend.com/downloads/docs/Declude_JunkMail_Manual.pdf) but don't see any references to the PATH varible or writting rules formating.

For instance, where is the [PATH] variable set since it fails to find "blacklistip.txt" using:
[PATH \blacklistip.txt <-- default setting

or
[PATH ]\blacklistip.txt

Log results:
02/09/2018 08:43:57.575 75196965 fromfile: Could not load [PATH]\blacklist.txt [3].
02/09/2018 08:43:57.778 75196965 Could not load ipfile [PATH]\blackip.txt.

And then when uncommenting rules the same issue happens:

FILTER-ADULT filter declude\filters\FILTER-ADULT.txt x 0 0

FILTER-DRUGS filter declude\filters\FILTER-DRUGS.txt x 0 0

FILTER-MEDICAL filter declude\filters\FILTER-MEDICAL.txt x 0 0

FILTER-ADULT filter [PATH]\Declude\filters\FILTER-ADULT.txt x 0 0

FILTER-DRUGS filter [PATH]\Declude\filters\FILTER-DRUGS.txt x 0 0

FILTER-MEDICAL filter [PATH]\Declude\filters\FILTER-MEDICAL.txt x 0 0

Resulting log records:

02/09/2018 08:44:35.139 75196968 Could not load filter file [PATH]\Declude\filters\FILTER-ADULT.txt.
02/09/2018 08:44:35.139 75196968 Could not load filter file [PATH]\Declude\filters\FILTER-DRUGS.txt.
02/09/2018 08:44:35.139 75196968 Could not load filter file [PATH]\Declude\filters\FILTER-MEDICAL.txt.

Hi Steve. The [PATH] is the path to the filters you are using or want to use. For example, if you have Declude filters located at C:\Smartermail\Declude\Filters, your lines in the global.cfg should look like this...

FILTER-ADULT filter C:\Smartermail\Declude\filters\FILTER-ADULT.txt x 0 0

FILTER-DRUGS filter C:\Smartermail\Declude\filters\FILTER-DRUGS.txt x 0 0

FILTER-MEDICAL filter C:\Smartermail\Declude\filters\FILTER-MEDICAL.txt x 0 0

Yes, I figured that out though originally thought it a variable...

One issue I did have was following a Anti Spam sheet that was to replace Bruce Barnes sheet but IF you also use Declude those same settings are present in the default declude scans. Hense, Double Points!

In other words, we were running the same rules twice so incurring higher than expected spam points.

Yes, that is correct. You should either use Declude or the settings in our white paper, but not both because double scores will happen. She sheet is for people who are not using Declude :)

Linda, Any tips for using Declude to screen Countries? For instance I want to exclude Germany from incoming emails.

MAIL DETAIL:
X-Country-Chain: GERMANY->destination

Is it simple a matter of allowing FILTER-COUNTRY.txt and then uncommenting:

#GERMANY
COUNTRIES 0 CONTAINS DE
MAILFROM 0 ENDSWITH .de

Do the zeros then take on our weight value?

Hi Steve. Yes, it's a simple matter of allowing the FILTER-COUNTRY to run and then uncommenting those lines. Yes, the zeros are the weight value. If you want to completely filter out all email from Germany, you would need to make those values higher than your delete weight. Also, at the top of the filter you will see this line... MAXWEIGHT 10... that means that the maximum weight this filter will apply if triggered is 10. You may want to comment out that line or change it to a value which matches whatever weight you choose for Germany.

Hi Linda, thanks for the details on Filter Syntax

I found the following in the Country Filter:

#GERMANY
#COUNTRIES 0 CONTAINS DE
#MAILFROM 0 ENDSWITH .de

Though updated it with to use the Perl RegEx:

# ---------------------- #
#GERMANY
COUNTRIES 10 PCRE (DE)
MAILFROM 5 ENDSWITH .de
COUNTRY 3 PCRE (DE)
REVDNS 3 PCRE (?i:\.de$)
MAILFROM 2 PCRE (?i:\.de$)
HELO 2 PCRE (?i:\.de$)

# ---------------------- #

Looking at my filter today I see it reverted and there is a backup called:
"FILTER-COUNTRY_safe_save_161444.txt"

I'm expecting this is due to an update to the Filters on your side? I do have a Cron / Windows Task set to update the Filters. I'll disable that if it is creating a case where changes are overwritten.

Couple Questions, I created a custom filter (based on the porn filter) as follows:

_______________________________________________________________________________

#LAST UPDATED 2/23/2018
#SKIPIFWEIGHT 25
MINWEIGHTTOFAIL 4

TESTSFAILED 3 PCRE (SNIFFER-PORN)

#--------------------------------------------------------------------#
# EXCEPTIONS #
#--------------------------------------------------------------------#
TESTSFAILED END PCRE (IADB|BONDEDSENDER|GOOD-REVDNS)
BODY END PCRE (?i:Content-Transfer-Encoding\: base64)

#--------------------------------------------------------------------#
# MAILFROM #
#--------------------------------------------------------------------#
MAILFROM 20 PCRE (?i:adultmailer-bounces@)

#--------------------------------------------------------------------#
# SUBJECT #
#--------------------------------------------------------------------#

SUBJECT 15 PCRE (?i:(Shark Tank))

#--------------------------------------------------------------------#
# BODY #
#--------------------------------------------------------------------#
BODY 30 PCRE (?i:\https://www.exclaimer.com/email-signature-handbook/\b)

_______________________________________________________________________________

"TESTSFAILED 3 PCRE (SNIFFER-PORN)"
Does this pertain to IF Sniffer is running and has encountered 3 positive hits as spam, and if so ignore this Filter?

The only filter lines I care about are the Subject where I have this coded to look for "Shark Tank" without regards to Capitalization (?i:)
Also check the Body for the noted string as I found a large number of emails having that pattern for obfuscation.

SIDE NOTE:
How hard would it be to create a filter that looks for repeating patterns that would be useful as the "obfuscation" patterns are used to thwart common anti-spam filters. If we could have a Filter that looked for X number of Characters that "repeat" we could catch a lot more Spam.

For instance: IF repeat chars x = Y, length = Z then Weight = W
So if we set "repeat chars" as 3 then "length" = 24 and Weight = 15
we would have a rule that looks for a repeating pattern of 24 characters found to repeat 3 times, then we assign a weight of 15. The "length" Content/Pattern would have to be a dynamic variable which is likely the issue that makes this difficult to create.

I keep finding content like the following which is a bunch of random characters or repeating html then a Dictionary Word appended to each line:

....<img class="EmojiInsert" id="OWAEmoji147586" alt="?" style="font-family: "Gothic, Arial, Comic-Sans"Apple Color Emoji", " "Segoe UI Symbol", Android Oreo, font-size: 22px; vertical-align: top;" src="cid:CHCO

I'll be happy when someone figures out how to use BlockChain as a mini SmartContract to validate legitimate emails prior to delivery... :-)

Hi Steve. To answer your questions...

1.) In reference to your FILTER-COUNTRY being overwritten... I apologize, I should have mentioned this before... If you have a Windows Task set up to download the new filters from our website each day, anything you change will be overwritten. The best thing to do would be to name your current FILTER-COUNTRY.txt to FILTER_COUNTRY.txt so that it does not get overwritten when a new FILTER-COUNTRY.txt is downloaded automatically. Also, remember to change the line in your global.cfg for the filter to...

FILTER_COUNTRY filter [PATH]\Declude\filters\FILTER_COUNTRY.txt x 0 0

2.) In reference to "TESTSFAILED 3 PCRE (SNIFFER-PORN)". If you are using the external Message Sniffer within Declude, you can break it down into specific tests such as SNIFFER-PORN, SNIFFER-SPAMWARE, SNIFFER-SCAMS etc... If you have your external Sniffer set up this way and you are using the porn filter in Declude and it is triggered, the TESTSFAILED 3 PCRE (SNIFFER-PORN) line will add 3 points to a message if SNIFFER-PORN is triggered as well.

3.) Is there a specific, repetitive string that you want to block currently, or are you simply asking if this is possible with Declude filters?

Thanks Linda,
As far as a "repetitive string" I was only floating the idea that a dynamic solution would be likely since the whole point of these dictionary words and random character strings is to get around spam filters.

Here is one I got today :

I already had a rule looking for :
(}>}**})_)\}}#*{)}})*^)]>*)?}}^{\}}!^{{}*:>{*<{}/}*}}}(){)^]^}

But as I see their patterns change, and it looks random, it's unlikely we can create a rule that would catch these (unless it was dynamic matching looped strings).

Thanks again for your reply.

Do you have any other examples of this? If yes, can you post the headers from a few messages like this? I may have a better solution for you.

Thanks for the samples. Since these messages are already moved to the Junk E-Mail folder, I'm assuming you want to stop them completely for landing in any folder and that is why you are inquiring about a filter? I just want to make sure I understand your end-goal. I noticed that all of these examples have one thing in common... they all triggered Declude's SPAMHEADERS test. The SPAMHEADERS test checks the email for headers that are common in spam, but not common in
legitimate email. This test is very similar to the BADHEADERS test, except the problems this test looks for are not RFC violations, so there's a good chance the test will catch a small amount of legitimate email (typically mail sent from mail clients written by webmasters rather than programmers). In my experience, this test catches very little legit email. Since this is the case, what I can do is write a filter that will trigger on all email which fails the SPAMHEADERS test and I can show you how to tell Declude to move it to a folder so you can review the messages. If you see that the messages that are triggered are consistently spam, I can then show you how to configure Declude to delete the messages instead of sending them to a folder for review. Are you open to giving this a try?

Sounds like a plan. I will speak with you via direct email to help you get this set up and then I we can report back here to let everyone know if it worked or not and then I can share what I did with the community. I just don't want to clog up the thread with configurations if they don't work for you. :)
