Marking HAM as good mail

Hi,

My boss is getting HAM mails from two addresses which are always marked
as SPAM.

I've seen that lowering the sa-learn threshold is not an option.

Is there a way to configure SA to stop marking those two specific
addresses as SPAM ?

Any help would be appreciated.

Warm Regards

Are you using the Botnet plugin?

If so, I'd add an exemption for their IP address to your Botnet.cf file.

It looks like what you'd need, if you are using Botnet, is either:


botnet_skip_ip        ^81\.92\.203\.3$

and/or

botnet_skip_ip        ^84\.18\.242\.136$


Depending on whether your scanning machine is the 
mx1.netcanvas.com/gauguin.netcanvas.com machine.  If it is, then use the 
2nd config line I gave, if it's not, then use the first one.


If you're not using Botnet, then ignore this message :-)

not now, but it was marked as spam when it was delivered. maybe 
dcc/razor (or spamcops?) was hit at that time. Unfortunately, it's too 
late to know (unless the infos are in your logs).

you'll need to modify your filter as I said before (add the list of 
rules to the X-Spam-Status header, so that you know what matched at the 
filtering time).

Strange, it has only 4.1 points, but is marked as SPAM!

you should configure your filter so that the X-Spam-Status header shows 
the tests that were hit.

now, take one of the messages and run "spamassassin -t" on it and show 
these tests (at the end of the report).

...oookay, someone better-versed in qmail-scanner will have to 
interpret this. I can't. It sure looks to me like it shouldn't be 
classified as spam.

Also: you may want to upgrade your SpamAssassin install to 3.1.8, 
3.1.0 is rather old and is subject to DoS attack.

Look at the config documentation for the whitelist_from_rcvd and 
whitelist_from_spf options. 

Can you post the list of rules that these mails are hitting (the 
X-Spam_Status header)?
