"insider information" slipping through

Can someone try and help me understand why this keeps slipping through.. in 
2+ days I have 40 or more of these to various addresses of my own on the 
server

Scored 7.4 on my setup.  Notice where it got most of the score:

Are you using Pyzor and DCC checks?

Are you running any network tests? Any SARE rule sets installed? Steve Basford 
does a fantastic job with his add-on clamav signature files for phishing and 
scam messages. This one was tagged as X-Spam-Virus: Yes 
(Email.Stk.Gen124.Sanesecurity.06122204). But even without the clamav tag 
this would have still been picked up as spam.

I, like Chris who posted results, don't have hardly any slipping through 
here either. I don't have Pyzor, DCC or Razor running and have bayes 
trained up. I do keep rules that I keep updated on a daily basis using 
sa-update. Here is a header from one such message that was trapped:

X-Spam-Level: xxxxxxxxxxxxxx
X-Spam-Status: Hits:14.6 Learn:no Tests:BAYES_99,HELO_DYNAMIC_IPADDR,
	RCVD_FORGED_WROTE,SARE_LWSHORTT,SARE_MLB_Stock1,SARE_MLB_Stock2

I do not have that issue.  Are you using sa-learn to learn the messages 
as spam?

"Present" slipping through - same as "insider information"

Posted by Vernon Webb <ve...@comp-wiz.com>.
I have a ton of these emails getting through that have the sender's name and the word 
Present getting through and they are the same as the insider information from last 
week. I have MailScanner, SpamAssassin, SARE, Botnet, Razor2, Pyzor, ClamAv and f-prot 
all installed and as far as I know working properly. Anyone else having this issue?

Thanks

Re: "insider information" slipping through

I've been following this thread as I am also receiving this SPAM and it is not labeled 
as such. Looking through old SPAM I have I noticed that I have most of the things 
mentioned in my headers for SPAM that I do have, however I know I have PYZOR installed 
but am seeing nothing labeled with the correct heading for PYZOR. Is there something 
that needs to be turned on in SA that will enable it? If so where?

Thanks

Re: "insider information" slipping through

Thanks every one.. I see that I really need to tweak my SA, I am not using
many of its features evidently..  I never saw any rule that would mark a
mail because ClamAV found a virus attached.. I can;t find anywhere this
RCVD_FORGED_WROTE rule either.. that alone would have made a huge difference
and gotten rid of it, almost every one I get is scored at 4.0 or higher

My personal SA is set to 4.9 and I have Eudora filter any score over 4.0 to
its own mailbox so I can see what's going on.. almost every one of these end
up in there..

Of course 15 of those points came from the clamav and botnet plugins. I didn't 
see any bayes score on your sample. You can always go and save these then run 
sa-learn --spam against them. I also don't see any network test, do you have 
them enabled? Any of the above would have been enough to kick it over the 
threshold to spam.
