Spamassassin Question

Postby dg_w » Thu Jan 12, 2006 4:24 pm

Think I have clam setup now .. thx .. And when I look in the headers spamassassin is running... However even on high scores 8 and 9 (default is 5) the [SPAM] header is not being attached .. Mail sent as normal ? Does this have to be setup per user ?
Default /etc/mail/spamassassin/local.cf


# These values can be overridden by editing ~/.spamassassin/user_prefs.cf
# (see spamassassin(1) for details)

# These should be safe assumptions and allow for simple visual sifting
# without risking lost emails.

Are you passing the -m flag when you start the spamass-milter? Check your init script. Look for a line that says something like:

EXTRA_FLAGS="-m -r 15"

The -m flag disables subject rewriting (you can still examine the full headers to see the result of the scan). The "-r 15" will drop all messages that score 15 or higher.


The spamass-milter man page has more information.

No they are # out
so not that ,

Spamd is starting with

# Options to spamd
SPAMDOPTIONS="-d -c -m5 -H"

Guess thats ok ... All default options.. Mail is being checked...Its in the headers
tail /var/log/mail/log

Milter add: header: X-Spam-Status: Yes, score=7.2 required=4.0 tests=ALL_TRUSTED,URIBL_AB_SURBL,\n\tURIBL_JP_SURBL,URIBL_OB_SURBL,URIBL_SC_SURBL,URIBL_WS_SURBL \n\tautolearn=no version=3.0.4

But the message comes through as normal ?

If I try the "test" send mail supplied with spamassassin

Sorry for the long file.... It appeats spamassassin \ milter scaned the mail, then rejected it ? The mail is not sent through to the mail box ..

I like the idea of rejecting mail, for maybe 4.5 and above ... But I can not see how its doing this form my basic as per install config file ?

This may not be the cause of your problem, but for the sake of completeness...

The config settings that are responsible for the behavior you are witnessing are not part of the normal spamassassin config file. Sendmail uses the spamass-milter plugin. What are the flags you are using to start spamass-milter? On Fedora, they appear in two places, within the init script iteself (/etc/init.d/spamass-milter), or in /etc/sysconfig/spamass-milter. What are the contents of those two files?

Thr spamass-milter (.etc.init.d/

start)
start
;;
stop)
stop
;;
restart|reload)
restart
;;
condrestart)
[ -e /var/lock/subsys/$prog ] && restart
RETVAL=$?
;;
status)
status $prog
RETVAL=$?
;;
*)
echo $"Usage: $0 {start|stop|restart|condrestart|status}"
RETVAL=1
esac

exit $RETVAL

And in /etc/sysconfig
### Override for your different local config
# SOCKET=/var/run/spamass.sock

### Default parameter for spamass-milter is -f (work in the background)
### you may add another parameters here, see spamass-milter(1)
# EXTRA_FLAGS="-m -r 15"

I have not made amy changes to files or scripts, just installed the rpms ..
Hope these help :)

Thank you

Please post the entire contents of:

/etc/init.d/spamass-milter
/etc/mail/sendmail.cf

thx for the assisstance


My OS is Redhat ES 4
Spamassassin (as installed with RH) spamassassin-3.0.4-1.el4
Spamass-milter spamass-milter-0.3.0-1.2.el4.rf
sendmail-devel-8.13.1-2
If I
[root@akserver init.d]# chkconfig --list|grep 'spamd\|spamass-milter'
spamass-milter 0:off 1:off 2:off 3:on 4:off 5:off 6:off
No Spamd ?
I have not installed a spamd.rpm ? Though on
service spamassassin restart
Shutting down spamd: [ OK ]
Starting spamd: [ OK ]
So I guess its there ?

chkconfig --list|grep 'spamassassin\|spamass-milter'

#
# EXTENSIONS These extensions will be advertised by the EHLO reply
# DOMAIN_NAME Local host FQDN
# LOCAL_NAMES Local aliases of DOMAIN_NAME
# DEFAULT_SMTP Either the name of a program (which must begin with
# a "/") or a hostname and optional port number. The
# default value is "/usr/sbin/sendmail -bs". Note that if
# mail is being re-directed to another machine, then that
# machine should be able to deal correctly with addresses that
# are nominally local to the originating machine.
# MAX_HOP_COUNT If the number of Received: header lines in a message sent to
# the relay exceed this number then the message will be
# rejected by the relay. The default value is zero and any
# non-positive value is interpreted as infinity. The default
# value means that no loop detection is done by the relay,
# any loop detection will only be done by sendmail.
# GREETING This is the text after the domain on the connection
# greeting line.
# LISTEN_PORT Alternative port to listen to, default is "smtp" port

So it identifies it , and says it has added the tag , though it does no appear in the recieved email >?

Maybe found it !

Postby dg_w » Mon Jan 16, 2006 6:40 am

Maybe found the cause ?
The spamass-milter startupscript
/etc/init.d/spamass-milter

### Default variables
SOCKET="/var/run/spamass.sock"
EXTRA_FLAGS="-m -r 15"
SYSCONFIG="/etc/sysconfig/spamass-milter"

That -m could be causing the issue ?

Sorry for the delay in getting back, I was called away over the weekend.

That is the "m" I was referring to in my earlier posts. In all liklihood, that is the culprit. The "r" flag is the one that is causing your messages to be dropped.

Comment/change them and restart the spamass-milter service.

Check the man pages for spamass-milter for more detailed information on the flags available.

Don't worry about the missing spamd service on RedHat. RedHat prefers to call the service spamassassin. Once you start it, you'll find spamd in the output of ps. Just make sure that both the spamassassin and spamass-milter services are running and configured to start on boot.
