redis, make it clusted

do you really need it ?

redis is not that stable in gentoo

spamassassin redis plugin does not support clustered redis yet imho

so its in vein imho

spamassassin is opensource feel free to make a bayes sql patch that

Re: Amavisd and Bayes (again...)

[Alexander Masidlover]

So, in doing the first part of the below (adding use_bayes_rules) I spotted 
that in the debugs there was a tainting error in an eval of Spamassassin Logger 
module shortly after the bayes module initialised.

I removed -T from the beginning of amavisd and now I’m getting BAYES headers 
when amavisd runs spamassassin…

When I have a bit more time I’ll revert my change and try and track down what’s 
going on with the taint error since its less than ideal from a security 
perspective to just disable tainting!

Thanks, I had been wondering about moving to SQL storage as we get a reasonably 
large volume of email through; however, I’m a bit concerned about doing all the 
set-up and still getting the same result!

The thing that’s throwing me is that as far as I can tell its actually managing 
to write to the bayes tokens files when it learns spam, but doesn’t seem to be 
using them in spam checking (apart from in standalone mode).

Re: Amavisd and Bayes (again...)

[Alexander Masidlover]

Thanks, but sadly not; the debugs show its definitely opening the same set of 
files.

RE: Amavisd and Bayes (again...)

[Dino Edwards]

Why don't you do the following.:



Edit your SA local.cf file and make sure the following lines are in it. NOTE 
the bayes_path, set that to a directory of your choice. Please also note that 
the last bayes of that path is NOT a directory but it's simply the prefix of 
that files in that directory (bayes_journal, bayes_seen, bayes_toks) but it has 
to be set that way in local.cf in order for this to work. So, if you were to 
use the path in my example, you would simply create the directory /opt/sa-bayes/



#bayes

bayes_path /opt/sa-bayes/bayes

bayes_file_mode 0777

use_bayes 1

use_bayes_rules 1

bayes_auto_learn 0





What I would do next, is take the bayes files from your current bayes directory 
and move them to that new directory you created. The new directory should look 
like below. NOTE the amavis user is the owner of that directory, you usually do 
that with chown -R amavis:amavis /opt/sa-bayes/



pwd

/opt/sa-bayes

Spamassasin and babes work perfectly well when I run mail through SA myself. It 
is when amavis does it that bates doesn’t work.

I have the root bayes files linked to mavin’s home directory and have 
permissions set so they are readable. Still doesn’t work.

I’ve posted a couple of times about the same exact issue with amavisnot using 
bases and so far no one has been able to provide any guidance as to why.

For now, I’ve given up. AMavis still catches a lot os spam without bases, and 
then I manually run received mail through SA again. It’s ugly, but it works.

Amavisd and Bayes (again...)

Hi,

I'm currently being deluged with spam and have been trying to use BAYES
filters to try and get rid of some of it. I've made a lot of progress
but am now very stuck.

I have go to the point where I have (temporarily) given the amavis user
a shell and when I run spamassassin on an email from the command line I
get:
