Subject: Re: [Dspam-user] New installation Centos 6 + postfix + dspam
On Jun 15, 2012, at 1:08 AM, Manel Gimeno Zaragozá wrote:hello,
I'm trying to configure an installation of dspam with postfix setup in Centos6.
My problem is that I'm not able to train dspam succesfully. I've installed
dspam from rpm, so I've not compiled it.
Here is my configuration:
Postfix(25)-->Dspam(dspam.sock)-->postfix(10026)------->Remote
Postfix(25)-->Cyrus
But when I try to report an spam message, I forward this message to
s...@pre.ddol.es and in maillog I got:

It looks like the mail is going again to "dspam" and a new "Signature" is
created. Anyway, I think dspam is not learning anything because the
"X-DSPAM-Probability" is always 0.0000.
I'm not sure If I'm misunderstand something or I'm doing something wrong. Other
thing i'm worried about is, I'm using thunderbird to read and forward messages
and I don't if this is the correct way to do it.
If you need more information, please tell me.

Thanks for the response, but I do not know how to force that either. Anyway,
I've been doing test and the only way that my dspam is learning is if I'm using
manual "train", I mean, executing in console
/usr/local/bin/dspam --source=error --class=innocent --user
mgime...@pre.ddol.es --signature='2,4fdf050a25591594210633'
then, dspam is learning and I can see in the user log the following line:
cat /usr/local/var/dspam/data/pre.ddol.es/mgimeno2/mgimeno2.log
1340016068 F <None Specified> 2,4fdf050a25591594210633
<None Specified> Retrained
But I can not do it automatically when I forward the email to s...@pre.ddol.es
or h...@pre.ddol.es
Could please someone guide me to configure it?
Thanks
