Re: Spamassassin rewriting headers of messages that are not marked Spam

2010-04-29 Thread Alex
Hi,

 This is the entire content of my local.cf:

 required_hits 5
 report_safe 0
 rewrite_header Subject [SPAM]

I don't think that's the best configuration either. You should start
with a default local.cf, then. You might also try enabling some
debugging to trace the loading of plugin-ins and rules. If you're
using amavisd you should be able to do something like this:

amavisd -c /etc/amavisd.conf debug-sa foreground 21 | tee
/var/log/amavisd.tmplog

You can then view /var/log/amavisd.tmplog from the top to see exactly
what it is doing. Amavis will also be live, listening for incoming
mail, so you can trace it in real-time.

If you're not using amavisd, (and even if you are, actually), you can
run the following to produce similar output:

spamassassin -D config --lint 21 | tee /var/log/spamassassin.tmplog

HTH,
Alex

 March isn't so suddenly. Why is it a problem now and not last month?
 
I'm tolerant. However, my tolerance has limits, and I've reached them.

It's happening on 90%, and I'm not able to discern the pattern of the other
10%. Yes I'm sure it's my system, because the header shows xspam-prev-header
without [SPAM] in it. That means that spamassassin admits that it changed
the header and added [SPAM] to it.

 That says that it isn't spam, so it doesn't seem likely that your
 system would be rewriting the subject header to say that it's spam.
 
It seems that my system shouldn't be doing it,  but it is, which is the
problem.

Just to be sure it *is* your SA installation that's writing this, try
changing that (temporarily) to something like: 

rewrite_header Subject [SPAM Test]

and see if it really is your SA doing the re-write. Don't forget to
restart spamd.

Here's an example:

X-Spam-Status: No, score=3.9 required=5.0 tests=AWL,BAYES_50,
DNS_FROM_OPENWHOIS,FH_DATE_PAST_20XX,HTML_MESSAGE,URG_BIZ autolearn=no
version=3.2.5


Not that this will fix your header-rewriting problem, but if you're seeing 
FH_DATE_PAST_20XX hits you _really_ ought to run sa-update and get your 
rules updated.

Hi,

 My spamassassin installation suddenly (since March) starting rewriting the
 headers of messages that are not spam.

March isn't so suddenly. Why is it a problem now and not last month?
Are you sure it is your system that is rewriting the headers? Is it
happening on every email?

 X-Spam-Status: No, score=3.9 required=5.0 tests=AWL,BAYES_50,
 DNS_FROM_OPENWHOIS,FH_DATE_PAST_20XX,HTML_MESSAGE,URG_BIZ autolearn=no

That says that it isn't spam, so it doesn't seem likely that your
system would be rewriting the subject header to say that it's spam.
What setting do you have in local.cf for reporting? Check these
variables:

report_safe
clear_report_template
report
add_header all

 It's SpamAssassin 3.2.5 (2008-06-10) running on RHEL 5.5. Anyone have any
 ideas on what it might be or what to look for?

You should also verify the method by which the regular updates are
being applied, as the FH_DATE_PAST_20XX could be a sign of an
outstanding bug in the default v3.2.5 72_active.cf file.

Alex
