Hello everybody,
I have a problem with my dspam installation.
Here is what I want to do:
Let's say that my MX is mailsystem.com and that I have a test user
[EMAIL PROTECTED]
The MTA (postfix) is hosted on a machine mta.mydomain.com
The MDA (cyrus) is hosted on a machine mda.mydomain.com and communicates
with postfix via lmtp.
What I wanted to do basically was something like this:
SMTP lmtp lmtp
-----> MTA.mydomain.com -----> DSPAM.mydomain.com ----->
MDA.mydomain.com
DSPAM is using a mysql backend and postfix is using DSPAM as a
content_filter:
content_filter = lmtp:[dspam.mydomain.com]:24
What I could see with dspam_stats -H [EMAIL PROTECTED] was something
like this
[EMAIL PROTECTED]:
TP True Positives: 0
TN True Negatives: 100
FP False Positives: 0
FN False Negatives: 0
SC Spam Corpusfed: 0
NC Nonspam Corpusfed: 0
TL Training Left: 2400
SHR Spam Hit Rate 100.00%
HSR Ham Strike Rate: 0.00%
OCA Overall Accuracy: 100.00%
The point is that no spam were detected, and I'm sure there was...
So I decided to do a training of dspam this way:
I've downloaded 20021010_spam.tar.bz2 and 20030228_easy_ham.tar.bz2 from
http://spamassassin.apache.org/publiccorpus/
untar, and the run
# dspam_train [EMAIL PROTECTED] spam/ easy_ham/
every single spam was failed and detected as innocent e.g:
[test: spam ] 00013.d3f0b591a65f116ea5d9d4ad91 result: FAIL (Innocent)
[fn] Subject: Get the Child Support You Deserve
11.180
Retraining didn't help, and dspam_stats gave me the following results:
[EMAIL PROTECTED]:
TP True Positives: 0
TN True Negatives: 65
FP False Positives: 0
FN False Negatives: 14
SC Spam Corpusfed: 0
NC Nonspam Corpusfed: 0
TL Training Left: 2435
SHR Spam Hit Rate 0.00%
HSR Ham Strike Rate: 0.00%
OCA Overall Accuracy: 82.28%
I was getting mad so I've decided to change my configuration in a more
standard one, in order to reinject the mails back to postfix via SMTP.
Of course the result is the same.
I may have missed something... Is there something special with virtual
users or something. I've already RTFM or STFW ;-)
Don't think this have any importance but dspam is hosted on FreeBSD.
Thank you for your help
