RE: [Declude.JunkMail] Image spam

2007-03-08 Thread Dave Beckstrom
 

I'm confused.  I understood that if you host multiple email domains on a
mail server that you're considered a hosting company and can't purchase
commtouch?  At least I vaguely recall something to that affect.  I checked
Declude's site and I don't see commtouch listed on there anywhere (it used
to be) other than under technology partners.

 

Obviously, I'm missing something.  So what is the scoop?  

 

I need an image spam solution.  I followed this discussion, but I didn't see
much talk about what people are actually using that currently works well for
them.  

 

I would most appreciate it if you would share your method for dealing with
image spam.

 

We have on particular spam that comes through multiple times every day.  Its
getting tiring.  There isn't enough other things wrong with the message to
block it.

Declude and Image based spam - 4 methods

1. COMMTOUCH

Commtouch Recurrent Pattern Detection contains an intrinsic mechanism to
exact-match recurrent patterns across similar but not-identical messages.
However in the case of images, the minute the spammer makes even the
smallest changes to an image, the image-encoded data appears completely
different. Commtouch identified this trend in the earliest days of
image-based spam, and made the necessary enhancements to its detection
engine in order to defend against this new threat with a sophisticated
protection shield. Commtouch invested significant resources into developing
a method for decoding the images and then sampling them using the proven RPD
approach. The result is a significantly improved spam detection rate, while
maintaining the same low false-positive rate.

2. CLAMWIN

Using ClamAV as a virus scanner with Declude you can download the
MSRBL-Images.hdb file which has additional signatures (MD5 sigs) which
contains signatures created from images contained within spam emails.
http://www.msrbl.com/site/msrblimagesdownload

3. FILTER-CID

Identifies emails which contains images increasing the weight suffeciently
on spam messages to reach the spam threshold.

ORF by image spam detection capabilities, but can be used by Declude.

[Declude.JunkMail] Whitelist weirdness

2007-03-08 Thread Robert Grosshandler
Hi

We're getting certain e-mails whitelisted, and I'm not able to find where
we've done that to ourselves.

Here's a line from a whitelist entry I CAN find:

Skipping3 E-mail from IP 208.100.26.91; whitelisted [208.100.26.91]

Here's a line from the whitelist entry I CANNOT find:

Skipping4 E-mail from [EMAIL PROTECTED]; whitelisted [EMAIL PROTECTED]

We have the directive AUTOWHITELIST ON   -- could that be it?

Thanks

Rob

We see that a lot... where the user has their own email address in their
webmail contacts, which results in any spam sent to them that forges their
email address coming through.
