Nope, we're still running NT server with Exchange 5.5 (I told you it was
old).  Exchange can be accessed via LDAP though.

This looks really nice, but I ran it against my maillog, and it didn't come
up with any stats.  I assume that I don't have the proper information being
added to my logs.  Where can I configure my system to add the needed
information?  I'm using MimeDefang/SpamAssassin/Sendmail.

It only gives me 2 options, -t and -y for today  yesterday, respectively.
I tried both of those, plus no option at all, to process the whole logfile
(which contains logs from 12/4 through today), and the result is the same.
Nothing.

 Which version of SA did it come with? Three versions exist 
 that all behave differently. One is the version a fellow just 
 posted a pointer to, today. The other comes with SA. I am 
 running 3.0.5 here and use the version that came with 3.0.4 
 with edited default values. It was not changed for 3.0.5, 
 apparently.

I wasn't aware that one came with the SpamAssassin distribution.  A search
on my system did not reveal any copies of sa-stats.pl other than the one I
downloaded from http://david.hexstream.co.uk/linux/scripts/, mentioned
earlier in this thread.  I could not find the one you mention at the SARE
site.  Maybe I'm missing it, but I'd expect it to be under Tools, and it's
not there.

My SA was installed using YUM, so maybe the sa-stats.pl wasn't included with
that version (which is 3.04-2) in case you're wondering.  I guess I'll
download the tarball  pull the script from there.

RE: Stats question...

2005-12-08 Thread Brian Leyton
Ok, I downloaded 3.05, and tried the sa-stats.pl that comes with the
distribution.  Still nothing.

I'm pretty sure that the reason is that there isn't any information in the
maillog to process.  When I look through the maillog, I don't see anything
from SpamAssassin or MimeDefang at all.  There must be something that needs
to be written to the logs, that's not being written.

The man page says that sa-stats.pl parses spamd entries in the mail log.
I'm not running spamd (I'm running MimeDefang), so I assume that's part of
my problem.  Also - this server doesn't deliver mail directly - it passes
everything to an Exchange Server.  Does that make a difference?

 Thanks.  americanbroadcastdx.com was never on any SURBLs, so 
 it's probably the bug.  Please consider upgrading to 3.1 or 
 possibly even 3.0.5 as this may fix the bug:
 
   http://issues.apache.org/SpamAssassin/show_bug.cgi?id=3997
 
 The developers will know for sure about which versions the 
 patch is in.  Or you could perhaps apply the patch manually to 3.0.4.
 They would know that too.
 
 It may be worth asking if you have any unusual DNS 
 arrangement such as proxying firewalls, etc.

Nothing unusual there.  It uses the firewall (IPCop) as a caching DNS
server, and the ISP's DNS as a fallback (not that that would help if the
firewall were down).

I'll see what I need to do to update.  I think I used yum to install it in
the first place, but something's hosed in the package dependencies.  I'll
get to work on that  see if I can get a newer spamassassin installed.

Thanks for your help!

URIBL False positive

2005-12-06 Thread Brian Leyton
I'm relatively new to SpamAssassin, but I've managed to get it working well
in conjunction with MimeDefang.  I'm having a strange problem though, which
I hope someone can help me figure out.

I'm on a hobby mailing list, and occasionally emails to this list are being
tagged as spam by SpamAssassin, based on the website mentioned in the emails
being on multiple URIBL lists.  Strangely though, when I go to the SURBL
checker at rulesemporium.com, the site is NOT shown as being listed on any
of these lists.

Bayes correctly considers these emails to NOT be spam, but the 4 URIBL
positives are enough to put the score over the top.

I have included this domain in the whitelist in sa-mimedefang.cf, but that
doesn't help.

What might cause these lookups to return false positives?
